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.”

We've already seen a few shorts in the 'fake' AI space, says Muddy Waters' Block

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.

CNBC Daily Open: U.S. stocks retreat from highs as Broadcom leads tech sell-off

The sell-off in artificial intelligence stocks continued unabated Friday stateside. Broadcom shares tumbled more than 11% as investors grew concerned over lower margins and uncertain deals. Names such as Nvidia, Advanced Micro Devices and Oracle fell in sympathy, which caused major U.S. indexes to close lower.

It was a motif patterning the week. Even though the Dow Jones Industrial Average rose 1.1% week on week on the back of outperformance by financial stocks, tech names dragged down the S&P 500 and the Nasdaq Composite, which fell 0.6% and 1.6% respectively for the week.

That said, investors could have just been jittery amid the narrative of an apparent AI bubble, and were spooked by any sign of bad news. After all, Broadcom’s earnings — as well as its guidance for the current quarter — breezed past expectations.

“Frankly we aren’t sure what else one could desire as the company’s AI story continues to not only overdeliver but is doing it at an accelerating rate,” Bernstein analyst Stacy Rasgon, who has a “buy” rating on Broadcom, wrote in a Friday note.

Future prospects also look rosy, according to UBS. “We expect high profitability and the accelerating impact of the AI, power and resources, and longevity themes to drive 2026 performance,” said strategist Sagar Khandelwal.

But in the near term, investors may still be flighty, unless something concretely reassuring, such as Oracle achieving positive cash flow, reassures them the snapping sound is just a twig in the forest.

U.S. stocks dragged down by AI names. Major indexes fell Friday, a day after they hit record highs. Asia-Pacific markets traded lower Monday. South Korea’s Kospi retreated roughly 1.5% as of 2:45 p.m. Singapore time (1:45 a.m. ET), leading losses in the region.

Copper could hit ‘stratospheric new highs’ as hoarding of the metal in U.S. continues

Copper prices have hit multiple record highs this year, fueled by supply disruptions and as fears over U.S. tariffs have led to a surge in demand. The rally is set to continue into 2026.

Citi analysts expect prices of the red metal to skyrocket on the back of stronger demand led by the energy transition and artificial intelligence sectors. Electrification, grid expansion and data-center build-outs require large amounts of the metal for wiring, power transmission and cooling infrastructure.

U.S. President Donald Trump’s verdict on Europe: a “decaying” group of nations led by “weak” people. His criticism in a recent Politico interview adds to a tough period for the bloc, with challenges on multiple fronts testing European leaders in the final weeks of the year.

This week looks set to be critical, with a high-stakes summit in Brussels and the European Central Bank’s final policy meeting of the year. Key topics for this week include defrosting frozen Russian assets for Ukraine aid; EU vs. U.S. in trade and tech, and updated economic figures at the ECB meeting.
