Most companies are real, it's just that a good fraction of the work is mostly unnecessary. Partially because of the overhead of doing business activities that is unneeded most of the time, partly because we don't know what work will be useful, and partly for silly social reasons
I keep coming back to the idea that all the upheaval combined with all the new tools at our disposal will empower and motivate people to start businesses that challenge the status quo. I've lived long enough to see that play out at scale, it is basically how we got Google. That might not sound encouraging, but Google was once a really inspiring company and one of the best places to work.
