Dalton is an amazing and very cool guy, and when he left it was indeed a big hit to dev speed at first, but recently a few super smart and dedicated guys have been able to do a big jump in updating the base from 16.04 to 20.04 (which involved moving from upstart to systemd) and they are getting close to rebasing to 24.04 (target for this is this June in fact). Plus Waydroid support has gotten really good in the time since Dalton moved on, and snap support is getting worked on now as well.
Except within the USA, declining population growth could be reversed immediately simply by returning to our pre-1924 immigration laws (i.e. the Ellis Island era) that between 1890 - 1924 allowed the USA to have some of the largest economic growth it ever has done. Yet “conservatives” (better termed “regressives” or “reactionaries”) these days want to do the exact opposite, out of xenophobia.
