Med isnt immune to automation or remote work as well (telemedicine)...its surprising a bit. I would be really surprised if there isnt tons of automation 10-20 years from now.
Nurses are pretty well protected though.
Well plumbing has problems as well: cognitive requirements are not especially high so in theory many people can do it if they are trained. Many immigrants to the U.S probably consider it.
It's the same benchmark in the blog post, `railsbench`. So TruffleRuby already speeds up some Rails apps like that one but not every Rails app/program.
(TruffleRuby 3.27x, YJIT 1.33x on railsbench)
That's definitely possible but it can definitely still "go up" - even for years. We're already used to debt to gdp being around 130% in the U.S (which a decade ago would have been unthinkable), who says it can't go to 200%. These numbers lose their wow effect really quickly and we all get used to them.
In fact, breaking the current dynamic is so hard and risky that central banks are tempted to stretch the debt further and further to prevent a market crash and a recession.
And yet there's inflation for real now, a sign things maybe can't go on like this for long.
I really have no idea but I'm not brave enough to make predictions over such a random thing as where the economy goes next year.
