'No return on investment yet'

"It's all investment money, they're spending billions and trying to push AI into the market at every turn because they hope that there will be a return on investment at some point," said Rehak. "But that doesn't exist at the moment, not anywhere," warned the scientist.

Only once companies generate profits and financial benefits through AI applications can there be a true “use case,” he added. If this doesn't happen, "then all these investments will eventually collapse," predicted the researcher.

In his eyes, companies are currently at a crossroads.

"Market analyses are now asking, is the AI bubble bursting?" Rehak said. More and more experts and analysts fear that investment in AI is progressing too quickly.

Even the CEO of OpenAI, the software company behind ChatGPT, is sceptical about massive spending in the AI sector. According to a report in The Verge magazine, Altman said that the market for artificial intelligence is increasingly becoming a bubble.

So is the AI bubble about to burst?
