Linux changed the landscape of Unix. We can do it with phones too. The defeatist attitude, while potentially true, didn’t land us where we are today server side.

Linux was a one-time anomaly in a much simpler, wilder era without overwhelmingly dominant incumbents in the spaces that Linux eventually took over.

Linux was created in 1993, when the computing world was still understandable by a single human. This is no longer the case, hence why we haven't seen any new (hacker) operating systems since then.

A purely technical solution is insufficient. Put on your suit and prepare to play politics.
