I'm old enough to remember when the browser UI showed you each host it was contacting (if any) rather than just sitting there with no indication of whether forward progress is or is possibly going to be made...
Error/progress UX is perhaps the biggest regression in computer UX over the past few decades.
Then: exactly what's happening, detailed description of what went wrong sufficient to diagnose and fix the problem.
Now: fake percentage bar that moves asymptotically towards 100% while nothing happens, then "Something Went Wrong™"
@dalias @dragonarchitect Also on top of that making error messages indistinguishable from update/information messages is not good for user comprehension. In my experience it's very common for informational messages to be received by end users as errors and vice versa.
