Some additional points to consider:
1. Pay the workers in company scrip and relocate the workers to a company town. That way, all workers are fully dedicated to the company.
2. Start importing slaves from Africa again. It worked to build up massive wealth. Should do the trick for AI as well.
3. Abolish the 8 hour work day. No comment needed.
With these 3 simple tricks, you too can get 6-7 bazillion euro AI mammoths.
No, we don't need any slavery. The employees at these AI companies will almost certainly out earn most if not all other local white collar workers, while also getting top tier benefits. They can also quit at any time if they don't like it or don't think it is fair.
