At this point, it's obvious and clear that you can outwork these 996 companies by simply requiring employees work 7 days a week in the office.

What is preventing one of these 996 companies from doing that and taking the lead in their respective AI niche? If they really believe that an additional day is their competitive edge, that seems like a really easy moat to overcome for a competitor, and by that logic why stop there? Wouldn't you want to maximize your chances of success by requiring your employees work 7 days in the office?

Just have your employees work a full 7 days in the office. I'm not joking either. Would some CEO who has adopted this practice care to explain why they don't just make things simple and require their employees to report to the office 7 days per week? It's simple and will only select for the most hardcore of the hardcore. I'm actually surprised someone hasn't tried this yet.
