How did we go from having useful compiler errors to accepting “The compiler is unable to type-check this expression in a reasonable time” as a compiler error?

Computers are in regression.

@simonbs Computers are faster than ever, but software keeps getting slower. 😓
@autiomaa swift’s type inference is both magical and the root cause of all the slowness.
@paulgessinger There is type inference in a lot of other programming languages, but it's not the only reason for slow performance of compilers. 😓
