Meta‘s chief artificial intelligence scientist Yann LeCun has spent much of the past week sparring with Elon Musk over the Tesla CEO’s treatment of scientists and news organizations, and for spreading false conspiracies on social media.
“I like his cars (I own a 2015 S, and 2023 S), his rockets, his solar energy systems, and his satellite communication systems,” LeCun wrote about Musk on Sunday in a Post on X, the social media site that Musk owns. “But I very much disagree with him on a number of issues.”
The spat began days earlier, on May 27, after Musk took to X to encourage people to apply for roles at his AI startup, xAI. The company, which last week announced it had raised $6 billion, is in a battle for AI engineers with high-profile startups, such as OpenAI and Anthropic, as well as top tech companies, including Google, Microsoft, Amazon and Meta.
Meta is trying to differentiate itself in the world of large language models, or LLMs, which have powered the recent boom in generative AI product development. While LLMs from xAI, OpenAI and Google are closed and proprietary for now, Meta is touting its Llama family of models as open source, meaning other researchers can copy, tweak or otherwise use them for their own AI initiatives.
In response to Musk’s promotional post, LeCun wrote, “Join xAI if you can stand a boss who makes promises that can’t be met, claims AI will ‘kill everyone’ and spews wild ‘conspiracy theories on his own social platform.'”
They continued going at it on Monday after Dr. Anthony Fauci testified publicly for the first time since leaving the government in 2022. Fauci appeared before the House Select Subcommittee on the Coronavirus Pandemic, facing broad criticism from Republicans who have long claimed he lied about the genesis of Covid-19.
Musk, who has previously called for the prosecution of Fauci, posted on X, “Why do Dems love Fauci so much.” He also unfollowed LeCun.
In response to being unfollowed, LeCun wrote, “Must have been my tweet in defense of Anthony Fauci.”
He followed by writing, “Elon’s call for Fauci to be prosecuted and imprisoned is pretty high up on the scale of anti-science a–holery.”
While Musk and Meta CEO Mark Zuckerberg have engaged in a yearslong public dispute and were even goading each other for months last year about a possible cage match, few tech leaders have been willing to criticize Musk in the open or bet against his companies.
Microsoft co-founder Bill Gates previously shorted Tesla stock. Investor Mark Cuban criticized Musk over his opposition to corporate Diversity, Equity, and Inclusion (DEI) efforts. And Meta co-founder Dustin Moskovitz has accused Tesla of consumer fraud.
In posts on X and LinkedIn over the weekend, LeCun said he disagrees with Musk’s secrecy when it comes to developing new technology and products and the “blatantly false” predictions he shares with the public, in addition to how he chooses to share “dangerous political opinions” and conspiracy theories.
Musk said in a post on X Monday that LeCun has been “out of touch with AI for a long time.” A Google Scholar link shared by LeCun indicates he has published 80 technical papers since January 2022.
LeCun and Musk didn’t respond to requests for comment on Monday.
The “blatantly false” predictions LeCun referenced included Musk’s claims that artificial general intelligence would arrive next year and that Tesla would bring 1 million robotaxis to market by 2020.
The latter promise came on a call with investors in 2019. At the time, Musk said robotaxis would make Tesla a company worth $500 billion. Tesla’s market cap topped $1 trillion in 2021, but the company still hasn’t delivered a single robotaxi.
Musk has also shared lofty goals for his brain implant startup Neuralink. He’s claimed Neuralink’s devices could enable “superhuman cognition” and “solve” autism and schizophrenia. During a “show and tell” recruitment event in late 2022, Musk said he plans to get an implant himself.
The company has implanted its flagship system in one human patient so far and has not received FDA approval for its technology.
LeCun was also critical of how Musk takes credit for the work of others. He pointed out that Musk’s only technical publication on Google Scholar is related to Neuralink. It was published in the Journal of Medical Internet Research in 2019. Musk is listed as the lead author, while the blanket term “Neuralink” is listed as the second author.
“I’m sure the scientists who hide behind this collective name are super happy about that,” LeCun said on X. “I just hope they won’t die bitter and forgotten.”
It was a terrible start to November on Wall Street. The tech-heavy Nasdaq sank just over 3% in its worst weekly performance since early April. The S & P 500 fell 1.6% for the week. Both stock measures broke three-week winning streaks.This week’s market decline, which followed a strong October, can be chalked up to two reasons. First, investors grew concerned about the eye-watering valuations of stocks tied to artificial intelligence. Case in point: Nvidia lost its $5 trillion market cap designation in a weekly loss of 7%. The weakness in Nvidia was exacerbated by the realization that China would not be opening back up in a meaningful way for the powerhouse of AI chips. While management has not included China sales in its outlook for months, many investors still thought it could happen. Still, we maintain our long-held “own it, don’t trade” thesis on Nvidia. .SPX .IXIC 5D mountain S & P 500 and Nasdaq weekly performance Second, there were emerging signs that the government shutdown, now the longest in U.S. history, was starting to harm the economy. Job cuts last month reached their highest levels for any October in 22 years, according to Thursday’s reading from outplacement firm Challenger, Gray & Christmas. A day later, the latest monthly consumer sentiment survey from the University of Michigan registered nearly its worst reading ever. These reports from private organizations have taken on added importance since the shutdown, which started on Oct. 1 and has delayed most government economic data. During this week of market turmoil, we executed three trades. On Monday, we added to our Starbucks position. The stock has taken a beating with other restaurant names on fears of a weakening consumer. In this case, we think the decline is overblown. After all, the turnaround story under CEO Brian Niccol remains strong. “With shares trading back to their ‘Liberation Day’ tariffs lows in early April, we see this recent weakness as an opportunity to slowly scoop up more,” Jeff Marks, the Investing Club’s director of portfolio analysis, wrote in a trade alert. “Niccol has embarked on an ambitious plan to bring back the coffeehouse atmosphere and fix its stores through a new operating and staffing model called Green Apron Service . It’s taken a few quarters, but the turn has finally started.” The Club also snapped up more Boeing stock Tuesday. Shares dropped significantly after the aircraft maker’s earnings report last week, caused by a larger-than-expected charge on its 777X program. Yes, the quarter was a frustrating setback. But the decline presented a great opportunity for long-term investors like us. “The turnaround under Boeing CEO Kelly Ortberg is still progressing nicely, driven by better execution on its 737 program,” Marks wrote in a trade alert. “With production moving from 38 airplanes per month to 42 — then eventually 47 and 52 under FAA guidance in the future — Boeing’s ability to make and deliver more planes will lead to strong free cash flow generation in the years ahead.” The market’s pullback Thursday gave us a chance to buy more GE Vernova stock. Shares have tumbled as AI-linked names have been scrutinized for their valuations. That’s because GE Vernova is one of the world’s largest producers of gas-fired turbines, which are used to create electricity and electrification products found in data centers. The company’s sales heavily benefit from the insatiable demand for more energy due to the frantic AI infrastructure race. “We are using this downturn to buy more shares since we still have a positive long-term outlook on the need for increased electricity investment,” Marks wrote in another trade alert. Eli Lilly made headlines this week. President Donald Trump on Thursday announced a GLP-1 pricing deal with Lilly and rival drugmaker Novo Nordisk that would lower prices for certain weight-loss treatments in exchange for coverage in Medicare and Medicaid programs. This was huge news for Lilly because it can expand access to Zepbound, increasing the blockbuster weight-loss drug’s total addressable market. Eli Lilly is also behind GLP-1 Mounjaro, but it was not included in the deal. That’s not the only piece of good news for Lilly. Management announced positive mid-stage trial results for its experimental amylin obesity drug. The once-a-week shot called eloralintide was shown to help patients shed pounds while maintaining muscle mass. Shares of Eli Lilly were up 7% for the week. this week. Quarterly earnings and spinoff news were also in focus. Eaton delivered a mixed third-quarter report Tuesday morning, which beat on adjusted earnings per share (EPS) but missed on revenue and organic sales. Although the headline results were uneven, the Club still found bright spots in the release. Overall segment profit and profit margin, for example, beat expectations and reached new quarterly records. DuPont posted a beat on the top and bottom line Thursday morning — less than a week after the spinoff of Qnity Electronics. Shares of DuPont slipped right after because of noise around quarterly numbers due to the split and divestiture of its Aramids business. Still, the underlying fundamentals for the new DuPont look strong, and the stock was our biggest winner on the week, up 16.5% to nearly $40. The Club downgraded shares to our 2 rating . We also adjusted our price target to $44. Solstice Advanced Materials, which recently split from Club name Honeywell , reported earnings on Thursday with no major surprises. There was a 7% topline growth, which was provided when Honeywell posted its own results just two weeks ago. Plus, it was all fairly consistent with what was said at an investor day last month. Texas Roadhouse shared a mixed earnings report Thursday night, posting better-than-expected comps despite concerns of softening consumer spending. However, higher beef prices caused the steakhouse chain to raise its commodity inflation outlook, which has weighed on Texas Roadhouse’s profitability for some time. We’re not giving up on the Club stock yet. Wall Street heard from Qnity on Thursday night, too. Not earnings, we learned about those numbers when DuPont reported, but management delivered a business update after the close, which made us hopeful of the company’s position to keep growing from secular trends like AI in the years ahead. The Club issued a buy-equivalent 1 rating on the stock and a price target of $110. Qnity stock has been volatile and closed Friday just over $92.

State Street is reiterating its bullish stance on the artificial intelligence trade despite the Nasdaq’s worst week since April.
Chief Business Officer Anna Paglia said momentum stocks still have legs because investors are reluctant to step away from the growth story that’s driven gains all year.
“How would you not want to participate in the growth of AI technology? Everybody has been waiting for the cycle to change from growth to value. I don’t think it’s happening just yet because of the momentum,” Paglia told CNBC’s “ETF Edge” earlier this week. “I don’t think the rebalancing trade is going to happen until we see a signal from the market indicating a slowdown in these big trends.”
Paglia, who has spent 25 years in the exchange-traded funds industry, sees a higher likelihood that the space will cool off early next year.
“There will be much more focus about the diversification,” she said.
Her firm manages several ETFs with exposure to the technology sector, including the SPDR NYSE Technology ETF, which has gained 38% so far this year as of Friday’s close.
The fund, however, pulled back more than 4% over the past week as investors took profits in AI-linked names. The fund’s second top holding as of Friday’s close is Palantir Technologies, according to State Street’s website. Its stock tumbled more than 11% this week after the company’s earnings report on Monday.
Despite the decline, Paglia reaffirmed her bullish tech view in a statement to CNBC later in the week.
Meanwhile, Todd Rosenbluth suggests a rotation is already starting to grip the market. He points to a renewed appetite for health-care stocks.
“The Health Care Select Sector SPDR Fund… which has been out of favor for much of the year, started a return to favor in October,” the firm’s head of research said in the same interview. “Health care tends to be a more defensive sector, so we’re watching to see if people continue to gravitate towards that as a way of diversifying away from some of those sectors like technology.”
The Health Care Select Sector SPDR Fund, which has been underperforming technology sector this year, is up 5% since Oct. 1. It was also the second-best performing S&P 500 group this week.
Neurodiverse professionals may see unique benefits from artificial intelligence tools and agents, research suggests. With AI agent creation booming in 2025, people with conditions like ADHD, autism, dyslexia and more report a more level playing field in the workplace thanks to generative AI.
A recent study from the UK’s Department for Business and Trade found that neurodiverse workers were 25% more satisfied with AI assistants and were more likely to recommend the tool than neurotypical respondents.
“Standing up and walking around during a meeting means that I’m not taking notes, but now AI can come in and synthesize the entire meeting into a transcript and pick out the top-level themes,” said Tara DeZao, senior director of product marketing at enterprise low-code platform provider Pega. DeZao, who was diagnosed with ADHD as an adult, has combination-type ADHD, which includes both inattentive symptoms (time management and executive function issues) and hyperactive symptoms (increased movement).
“I’ve white-knuckled my way through the business world,” DeZao said. “But these tools help so much.”
AI tools in the workplace run the gamut and can have hyper-specific use cases, but solutions like note takers, schedule assistants and in-house communication support are common. Generative AI happens to be particularly adept at skills like communication, time management and executive functioning, creating a built-in benefit for neurodiverse workers who’ve previously had to find ways to fit in among a work culture not built with them in mind.
Because of the skills that neurodiverse individuals can bring to the workplace — hyperfocus, creativity, empathy and niche expertise, just to name a few — some research suggests that organizations prioritizing inclusivity in this space generate nearly one-fifth higher revenue.
AI ethics and neurodiverse workers
“Investing in ethical guardrails, like those that protect and aid neurodivergent workers, is not just the right thing to do,” said Kristi Boyd, an AI specialist with the SAS data ethics practice. “It’s a smart way to make good on your organization’s AI investments.”
Boyd referred to an SAS study which found that companies investing the most in AI governance and guardrails were 1.6 times more likely to see at least double ROI on their AI investments. But Boyd highlighted three risks that companies should be aware of when implementing AI tools with neurodiverse and other individuals in mind: competing needs, unconscious bias and inappropriate disclosure.
“Different neurodiverse conditions may have conflicting needs,” Boyd said. For example, while people with dyslexia may benefit from document readers, people with bipolar disorder or other mental health neurodivergences may benefit from AI-supported scheduling to make the most of productive periods. “By acknowledging these tensions upfront, organizations can create layered accommodations or offer choice-based frameworks that balance competing needs while promoting equity and inclusion,” she explained.
Regarding AI’s unconscious biases, algorithms can (and have been) unintentionally taught to associate neurodivergence with danger, disease or negativity, as outlined in Duke University research. And even today, neurodiversity can still be met with workplace discrimination, making it important for companies to provide safe ways to use these tools without having to unwillingly publicize any individual worker diagnosis.
‘Like somebody turned on the light’
As businesses take accountability for the impact of AI tools in the workplace, Boyd says it’s important to remember to include diverse voices at all stages, implement regular audits and establish safe ways for employees to anonymously report issues.
The work to make AI deployment more equitable, including for neurodivergent people, is just getting started. The nonprofit Humane Intelligence, which focuses on deploying AI for social good, released in early October its Bias Bounty Challenge, where participants can identify biases with the goal of building “more inclusive communication platforms — especially for users with cognitive differences, sensory sensitivities or alternative communication styles.”
For example, emotion AI (when AI identifies human emotions) can help people with difficulty identifying emotions make sense of their meeting partners on video conferencing platforms like Zoom. Still, this technology requires careful attention to bias by ensuring AI agents recognize diverse communication patterns fairly and accurately, rather than embedding harmful assumptions.
DeZao said her ADHD diagnosis felt like “somebody turned on the light in a very, very dark room.”
“One of the most difficult pieces of our hyper-connected, fast world is that we’re all expected to multitask. With my form of ADHD, it’s almost impossible to multitask,” she said.
DeZao says one of AI’s most helpful features is its ability to receive instructions and do its work while the human employee can remain focused on the task at hand. “If I’m working on something and then a new request comes in over Slack or Teams, it just completely knocks me off my thought process,” she said. “Being able to take that request and then outsource it real quick and have it worked on while I continue to work [on my original task] has been a godsend.”
