Can someone using modules chime in on whether they’ve seen build times improve?
Chuanqi says "The data I have obtained from practice ranges from 25% to 45%, excluding the build time of third-party libraries, including the standard library."[1]

It seems likely I’ll have to move away from C++, or perhaps more accurately it’s moving away from me.
why use modules if PCH on your diagram is not much worse in compile times?
If these aren't compelling, there's no real reason.
https://arewemodulesyet.org/ gives you an overview which libraries already provide a module version.
Log scale: Less than 3% done, but it looks like over 50%.
Estimated completion date: 10 March 2195
It would be less funny if they used an exponential model for the completion date to match the log scale.
I can’t deploy C++ modules to any of the hardware I use in the shop. Probably won’t change in the near-to-mid future. It seems likely I’ll have to move away from C++, or perhaps more accurately it’s moving away from me.

import std; is an order of magnitude faster than using the STL individually, if that's evidence enough for you. It's faster than #include alone.
