For sure! I expect some marquee libraries like ITK to adopt them as soon as it’s prudent (meaning when they can sunset support for older compilers), but most people won’t be using them.

I mean, most people don’t have to even really write templates code...

Oh right, but I meant even by people who do write templates haha. I'm wondering in what fraction of cases they'll actually use concepts when they potentially could.
