So, yes absolutely, administrative work now can finally be replaced, and we can free up all the tormented souls in these managerial positions to do something more meaningful with their lives.
There are also plenty of successful companies and projects without management too. Basically every 1-to-5ish-man consulting shop has zero managers and some of those do wildly well. Some of the best indie games, produced by teams of 3 or 4, had zero dedicated management. Most open source projects have effectively 0 management.
Valve, famously, kept a flat organizational structure for a long time, and certainly was somewhat successful.
These companies are even more stratified than before with the lumpenproletariat doing human-mechanized tasks while executives program their lives using software we write in exchange for the unbridled luxuries like the chance to own a roof over our head one day.
It's not exactly the future I wanted.
