I haven't tried it. I think the idea is really interesting but it always seemed to me like it was somewhat in contradiction with why people become employees in the first place. My perception is that people ultimately sort themselves into different roles in the workforce and those who are employees are doing it mostly because they want a consistent income every month, perhaps a social environment to participate in and a fair amount of direction. If you don't want those things you go freelance or become an entrepreneur.

When I look at past and current people I've managed my feeling is maybe 1 in 4 would respond really well to the "results only" workplace and the other 3 might quit.

I think the whole discussion of remote work is colored by the fact that there is a particular personality type - smart, introverted, self-motivated, results-oriented - which operates very well remotely. A lot of these people gravitate toward the tech industry. Some of them get a taste of remote and then they talk it up like it's the future of work for everyone because it is so great for them. I totally get it, I prefer remote myself, and if those people produce then I'm happy to let them be as remote as they want to be forever.

It's just that those people aren't 100% of the workforce (probably not even 30%).
