AI robots will exceed the working population within a few decades as more firms adopt AI agents and continue to squeeze costs, a former Citi executive warned on Monday.

Rob Garlick, Citi Global Insights’ former head of innovation, technology, and future of work, told CNBC’s “Squawk Box Europe” that as leaders continue to prioritize profitability, their human workers will be left in the dust.

“We have a leadership system in the economic terms and business terms that celebrates profitability,” Garlick said in a conversation with CNBC’s Steve Sedgwick and Ben Boulos.

“When you marry profitability up with the technology progress, we have the biggest trade in history coming, which is basically that artificial intelligence will be able to do more and more, better and better, cheaper and cheaper, and that will be able to substitute for people.”

Garlick, who recently authored “AI – Anarchy or Abundance? Why the Future of Work Needs Pro-Human Leaders,” explained that his previous research at Citi showed that the number of AI robots is going to skyrocket as a result of these business decisions.

“We’re going to go over the next couple of decades to more moving robots than the working population, and then you add on agents, little agents, and it is going to explode,” he added.

AI robots ranging from humanoids to domestic cleaning robots and autonomous vehicles are forecasted to increase to 1.3 billion by 2035, according to a 2024 Citi report led by Garlick. The number of AI robots would quickly increase to over 4 billion by 2050, per the insights.

The Citi report even measured how long it would take for a robot to pay for itself through the money saved by replacing a human worker, for example, a $15,000 robot would break even in 3.8 weeks for a $41 an hour human job, or 21.6 weeks for a $7.25 human job. Meanwhile, a robot that costs $35,000 would have a payback time of 8.9 weeks for a $41 an hour human job.

“You can already buy a humanoid today, which gives you a payback period versus human workers of less than 10 weeks,” Garlick told CNBC, citing a figure from his book. “Humans can’t compete on this basis.”

Microsoft’s Work Trend Index report showed that 80% of leaders expect AI agents to be largely integrated into their AI strategy within the next 12 to 18 months. AI agents are a type of software program that can make decisions and complete tasks without much human direction.

Meanwhile, McKinsey & Company’s global managing partner, Bob Sternfels, noted that the company currently employs 20,000 agents alongside 40,000 humans, in an interview with Harvard Business Review. A year prior, the company only had 3,000 agents, and Sternfels predicts that in 18 months from now, there will be an equal number of employees and agents.

Tesla CEO Elon Musk also shared similar views at the World Economic Forum’s flagship conference in Davos last month, saying that AI will likely surpass human intelligence by the end of this year.

“My prediction is, in the benign scenario of the future, that we will actually make so many robots in AI that they will actually saturate all human… there will be such an abundance of goods and services because my prediction is that there’ll be more robots than people,” Musk said.

Fears around AI replacing workers have mounted in the past year as major firms, including Amazon, Salesforce, Accenture, Heineken, and Lufthansa, have cited the technology as part of the reason for eliminating thousands of roles.

Kristalina Georgieva, managing director at the International Monetary Fund, told CNBC in January that AI is “hitting the labor market like a tsunami” and warned that “most countries and most businesses are not prepared for it.”

In the U.S., AI played a role in almost 55,000 layoffs in the U.S. in 2025, according to December data from consulting firm Challenger, Gray & Christmas.

However, some leaders are striking a more positive tone. Nvidia’s CEO Jensen Huang predicts that the “AI boom” will create six-figure salaries for the workers building AI and chip factories. Huang said the technology will boost skilled trade work, such as for plumbers, electricians, construction, and steel workers.

Software stocks have been hammered in recent weeks as investors worry about threats from artificial intelligence. In the startup world, Canva has been among the highest fliers due to its popularity with designers, but that market is showing vulnerability, with larger rival Adobe down 30% so far this year.

As Canva reckons with dramatic changes in the market, the design software vendor is getting acquisitive. The company said Monday that it’s purchased two startups — Cavalry and MangoAI — that stand to help it challenge Adobe.

Cavalry, a four-person startup, sells subscriptions to software for creating two-dimensional animations. MangoAI is a stealth-mode company, whose technology can be used for creating short videos for advertising. Terms of the deals weren’t disclosed.

Cameron Adams, Canva’s co-founder and product chief, told CNBC that customers have been asking what the company can offer in motion graphics. Cavalry, which Canva has used for its own projects, has gained attention among designers on social media as an alternative to Adobe’s After Effects for some work.

Canva will continue to operate Cavalry for people to use and buy independently, while also incorporating the animation technology into the core Canva product and the Affinity application for professional designers. Canva bought Affinity in 2024 and made it free in October.

Amazon, ByteDance, Google, and OpenAI all have employees that are paying customers, according to Cavalry’s website.

Canva plans to incorporate MangoAI into the Canva Grow advertisement generator, which is available through its business tier at $250 per person per year. The MangoAI technology is able to track video performance and make recommendations.

“There’s a whole bunch that goes into creating the right video,” Adams said. That includes “being able to cut stuff down, being able to repurpose content from other campaigns and put it together, being able to take a great call to action that happens at the end of one video and then append it to the hook that happens in another video,” he said.

“Analyzing all of that across your campaigns is the full vision of Canva Grow, and Mango will help enable that,” Adams added.

Canva said it ended 2025 with over $4 billion in annualized revenue, up 36% from a year prior. Adobe reported $6.2 billion in revenue for the November quarter, up 10%. Adobe’s market capitalization stood at $101 billion on Monday, while Canva said in August that it had been valued at $42 billion in a secondary share sale, before the recent plunge in software stocks.

Adams said Canva has seen instances of people directing generative AI models to create content such as slide presentations and social media posts. But AI can’t do everything, he said.

“AI is great at getting you to 80%,” Adams said. “That last 20% where you’re confident that you can push this piece of content out and truly represent your brand and speak to your audience and achieve the goals that you want to achieve is vital to have, and that last 20% is really tricky to do.”

Canva, which now has over 5,000 employees, is not currently raising a new funding round, Adams said.

“Our revenue growth has not stopped, our user growth has not stopped, and the quality of our product is getting better and better with the inclusion of AI,” he said.
