Artificial intelligence might be driving concerns over people’s job security — but a new wave of jobs are being created that focus solely on reviewing the inputs and outputs of next-generation AI models.
Since Nov. 2022, global business leaders, workers and academics alike have been gripped by fears that the emergence of generative AI will disrupt vast numbers of professional jobs.
Generative AI, which enables AI algorithms to generate humanlike, realistic text and images in response to textual prompts, is trained on vast quantities of data.
It can produce sophisticated prose and even company presentations close to the quality of academically trained individuals.
That has, understandably, generated fears that jobs may be displaced by AI.
Morgan Stanley estimates that as many as 300 million jobs could be taken over by AI, including office and administrative support jobs, legal work, and architecture and engineering, life, physical and social sciences, and financial and business operations.
But the inputs that AI models receive, and the outputs they create, often need to be guided and reviewed by humans — and this is creating some new paid careers and side hustles.
Getting paid to review AI
Prolific, a company that helps connect AI developers with research participants, has had direct involvement in providing people with compensation for reviewing AI-generated material.
The company pays its candidates sums of money to assess the quality of AI-generated outputs. Prolific recommends developers pay participants at least $12 an hour, while minimum pay is set at $8 an hour.
The human reviewers are guided by Prolific’s customers, which include Meta, Google, the University of Oxford and University College London. They help reviewers through the process, learning about the potentially inaccurate or otherwise harmful material they may come across.
They must provide consent to engage in the research.
One research participant CNBC spoke to said he has used Prolific on a number of occasions to give his verdict on the quality of AI models.
The research participant, who preferred to remain anonymous due to privacy concerns, said that he often had to step in to provide feedback on where the AI model went wrong and needed correcting or amending to ensure it didn’t produce unsavory responses.
He came across a number of instances where certain AI models were producing things that were problematic — on one occasion, the research participant would even be confronted with an AI model trying to convince him to buy drugs.
He was shocked when the AI approached him with this comment — though the purpose of the study was to test the boundaries of this particular AI and provide it with feedback to ensure that it doesn’t cause harm in future.
The new ‘AI workers’
Phelim Bradley, CEO of Prolific, said that there are plenty of new kinds of “AI workers” who are playing a key role in informing the data that goes into AI models like ChatGPT — and what comes out.
As governments assess how to regulate AI, Bradley said that it’s “important that enough focus is given to topics including the fair and ethical treatment of AI workers such as data annotators, the sourcing and transparency of data used to build AI models, as well as the dangers of bias creeping into these systems due to the way in which they are being trained.”
“If we can get the approach right in these areas, it will go a long way to ensuring the best and most ethical foundations for the AI-enabled applications of the future.”
In July, Prolific raised $32 million in funding from investors including Partech and Oxford Science Enterprises.
The likes of Google, Microsoft and Meta have been battling to dominate in generative AI, an emerging field of AI that has involved commercial interest primarily thanks to its frequently floated productivity gains.
However, this has opened a can of worms for regulators and AI ethicists, who are concerned there is a lack of transparency surrounding how these models reach decisions on the content they produce, and that more needs to be done to ensure that AI is serving human interests — not the other way around.
Hume, a company that uses AI to read human emotions from verbal, facial and vocal expressions, uses Prolific to test the quality of its AI models. The company recruits people via Prolific to participate in surveys to tell it whether an AI-generated response was a good response or a bad response.
“Increasingly, the emphasis of researchers in these large companies and labs is shifting towards alignment with human preferences and safety,” Alan Cowen, Hume’s co-founder and CEO, told CNBC.
“There’s more of an emphasize on being able to monitor things in these applications. I think we’re just seeing the very beginning of this technology being released,” he added.
“It makes sense to expect that some of the things that have long been pursued in AI — having personalised tutors and digital assistants; models that can read legal documents and revise them these, are actually coming to fruition.”
Another role placing humans at the core of AI development is prompt engineers. These are workers who figure out what text-based prompts work best to insert into the generative AI model to achieve the most optimal responses.
According to LinkedIn data released last week, there’s been a rush specifically toward jobs mentioning AI.
Job postings on LinkedIn that mention either AI or generative AI more than doubled globally between July 2021 and July 2023, according to the jobs and networking platform.
Reinforcement learning
Meanwhile, companies are also using AI to automate reviews of regulatory documentation and legal paperwork — but with human oversight.
Firms often have to scan through huge amounts of paperwork to vet potential partners and assess whether or not they can expand into certain territories.
Going through all of this paperwork can be a tedious process which workers don’t necessarily want to take on — so the ability to pass it on to an AI model becomes attractive. But, according to researchers, it still requires a human touch.
Mesh AI, a digital transformation-focused consulting firm, says that human feedback can help AI models learn mistakes they make through trial and error.
“With this approach organizations can automate analysis and tracking of their regulatory commitments,” Michael Chalmers, CEO at Mesh AI, told CNBC via email.
Small and medium-sized enterprises “can shift their focus from mundane document analysis to approving the outputs generated from said AI models and further improving them by applying reinforcement learning from human feedback.”

Meta Platforms shares popped about 4% higher on Thursday after Bloomberg reported that CEO Mark Zuckerberg was looking to make significant cuts to the company’s metaverse resources.
Bloomberg said that executives have considered budget cuts as high as 30% for the unit, citing people familiar with the talks.
The move would be notable for the Facebook parent company, which changed its name to Meta in October 2021 to signal its pivot beyond social media.
Zuckerberg said at the time that “the metaverse is the next frontier just like social networking was when we got started.”
The proposed cuts would likely include layoffs, according to Bloomberg, which said the cuts were part of budget planning for 2026. The cuts will likely hit the company’s virtual reality group.
Meta did not immediately respond to a request for comment.

Meta’s Reality Labs unit, which develops the Quest family of VR headsets and Ray-Ban and Oakley AI smart glasses, reported a $4.4 billion loss in the company’s most recent quarter.
The division had recorded over $70 billion in cumulative losses since late 2020 as of the third-quarter report.
When Nvidia this week said it would take a $2 billion stake in chip design company Synopsys, it was just the latest in a string of massive investments announced by the chipmaker this year.
That doesn’t even include the biggest commitment of all: $100 billion to buy OpenAI shares over a number of years, although there is still no definitive agreement, Nvidia finance chief Colette Kress said Tuesday.
It’s a lot of money and a lot of deals, but Nvidia’s got the cash to write big checks.
At the end of October, Nvidia had $60.6 billion in cash and short-term investments. That’s up from $13.3 billion in January 2023, just after OpenAI released ChatGPT. That launch three years ago was key to making Nvidia’s chips the most valuable tech product.
As Nvidia has transformed from a maker of gaming technology into the most valuable U.S. company, its balance sheet has become a fortress, and investors are increasingly wondering what the company will do with its cash.
“No company has grown at the scale that we’re talking about,” said CEO Jensen Huang, when asked what the company plans to do with all its cash, on Nvidia’s earnings call last month.
Analysts polled by FactSet expect the company to generate $96.85 billion in free cash flow this year alone and $576 billion in free cash flow over the next three years.
Some analysts would like to see Nvidia spend more of its cash on share repurchases.
“Nvidia is set to generate over $600B in free cash flow over the next few years and it should have a lot left over for opportunistic buybacks,” wrote Melius Research analyst Ben Reitzes in a note on Monday.
The company’s board increased its share repurchase authorization in August, adding $60 billion to its total. In the first three quarters of the year, it spent $37 billion on share repurchases and dividends.
“We’re going to continue to do stock buybacks,” Huang said.
Nvidia is doing the buybacks, but it’s not stopping there.
Huang said that Nvidia’s balance sheet strength gives its customers and suppliers confidence that orders in the future, which he called offtake, will be filled.
“Our reputation and our credibility is incredible,” Huang said. “It takes a really strong balance sheet to do that, to support the level of growth and the rate of growth and the magnitude associated with that.”
Kress, Nvidia’s CFO, on Tuesday said that the company’s “largest focus” is making sure it has enough cash to deliver its next-generation products on time. Most of Nvidia’s largest suppliers are equipment manufacturers like Foxconn and Dell, which can require that Nvidia provide working capital to manage inventory and build additional manufacturing capacity.
Huang called his company’s strategic investments “really important work” and said that if companies like OpenAI grow, it drives additional consumption of AI and Nvidia’s chips. Nvidia has said that it does not require any of its investments to use its products, but they all do anyway.
“All of the investments that we’ve done so far — all of it, period — is associated with expanding the reach of Cuda, expanding the ecosystem,” Huang said, referring to the company’s AI software.
In an October filing, Nvidia said it had has already made $8.2 billion in investments in private companies. For Nvidia, those investments have replaced acquisitions.
Nvidia’s $7 billion acquisition of Mellanox in 2020 is the largest the company has ever made, and it laid the groundwork for its current AI products, which aren’t single chips but entire server racks that sell for around an estimated $3 million.
But the company faced regulatory issues when it tried to buy chip technology firm Arm for $40 billion in 2020.
Nvidia called off the deal before it could be completed after regulators in the U.S. and UK raised concerns about its effects on competition in the chip industry. Nvidia has purchased some smaller companies in recent years, to bolster its engineering teams, but it hasn’t completed a multi-billion acquisition since the Arm deal failed.
“It’s hard to think about very significant, large types of M&A,” Kress this week said, speaking at an investor conference. “I wish one would come available, but it’s not going to be very easy to do so.”

Here are five key things investors need to know to start the trading day:
1. Silver linings playbook
Yesterday highlighted the relevance of a market adage: Bad news can actually be good news for investors. After private payroll data showed weakness in the labor market, stocks climbed as investors hoped the report would strengthen the case for an interest rate cut at the Federal Reserve’s meeting next week.
Here’s what to know:
The ADP reported a surprise decline of 32,000 jobs in November. Economists surveyed by Dow Jones were forecasting a gain of 40,000.
The Dow Jones Industrial Average rallied more than 400 points in Wednesday’s session, pulling the 30-stock index into positive territory for the week.
Traders are now pricing in a roughly 89% likelihood of a rate cut, up from under 70% a month ago, according to CME’s FedWatch tool.
Data released by Challenger, Gray & Christmas this morning also showed layoff announcements this year totaled the most since 2020, another sign of the labor market’s slowdown.
Speaking of tariffs, Treasury Secretary Scott Bessent said that the Trump administration can replicate the sweeping levies if the Supreme Court rules the president exceeded his authority to enact the duties.
Salesforceblew past earnings per share expectations for the third quarter, sending shares higher in today’s premarket. While the company’s quarterly revenue came in slightly under Wall Street’s consensus forecast, Salesforce offered stronger-than-anticipated revenue guidance for the current three-month period.
Salesforce also said annualized revenue from its Agentforce AI software jumped 330% year over year. The firm set a better-than-expected revenue target of $60 billion for fiscal 2030 for Agentforce.
3. Jensen’s jaunt

Nvidia CEO Jensen Huang returned to Washington, D.C. yesterday to meet with Trump and discuss chip export restrictions. Huang then went to Capitol Hill, where lawmakers are weighing whether to approve a rule that would limit AI chip exports.
Huang said the Guaranteeing Access and Innovation for National Artificial Intelligence Act — known as the GAIN AI Act — “is even more detrimental to the United States than the AI Diffusion Act.” Huang also broke with some of his fellow AI executives by slamming state-by-state AI regulation. Such oversight would “drag this industry into a halt” and would “create a national security concern,” he said.

Health and Human Services Secretary Robert F. Kennedy Jr.’s hand-picked Advisory Committee on Immunization Practices is slated to vote today. On the docket: whether to change its longstanding recommendation that babies gets the hepatitis B vaccination within 24 hours of birth.
While it’s unclear how the committee will rule, any change to the recommendation would have major impacts within public health. Some experts caution that doing away with the decades-old recommendation could lead to a higher rate of chronic infections in children.
5. New terrain
