A poorly-kept secret in Silicon Valley is that many "AI startups" started over the last few years are actually using humans, with a long-term plan to slowly decrease the amount of work the humans do using algorithms (generally based on machine learning, but not always) as well as more basic automation. In some cases they don't actually do any "AI" work for the company's first few years, and if they do, it's more like…
Only if the AI is going to work for sure.
There was a UK company, SpinVox, they were big 10 years ago, they did voice recognition of your phone calls and sent you a text. They raised huge, like 100M pounds. Granted not AI.
Turns out they were doing most of their transcription manually with hopes of going automated.
It was a huge blow up, it boiled to fraud.
This is close to Elizabeth Holmes territory kind of storyline.
So it's possible to do as you say, but there needs to be transparency.
Also, AI is an approach, not a market ... so I think they're going to end up like transistors or some other kind of thing, the knowledge will be embedded within companies, and not so many pure AI companies.
