> 4. Regulatory disadvantages: In everything from company regs, employee regs, unions, privacy regs, data portability regs, etc.

Agreed. My own anecdote: my company is global and for the past 6 months, we've been working on getting regulatory and legal approval for an LLM-based feature. The initial proposals of going live in all of our markets have been pared back to exclude Europe altogether due to the regulatory environment.

When I took part in company-wide gen AI councils that reviewed new product rollouts, it seemed like there was a definite hesitation from higher ups from pushing out any leading edge features to European markets. And it's not that the regulations would necessarily block these features from going live but that they'd increase implementation costs to the point where it wouldn't be worth it.
