Sorry I may have missed the sarcasm.

Your day job project takes half an hour to compile and you don't see the point in speeding that up?

It wasn't sarcasm. My "irrelevant" point meant "it's irrelevant for a factor in picking a language", as in "it doesn't significantly contribute to whether a project is possible in the long term".

If compile times are longer you just compile less often and write larger portions of code at a time and you generally keep writing code while it compiles.

Works when you've been using a minimal language like C for over a decade and you're an expert. For people learning a new language they constantly need to be recompiling to check their assumptions are correct, that's why it's so important for the masses.

If they're a new developer they're not going to be compiling a massive project over and over I would assume. They'd be writing small toys to learn the language.

GP did say it is a nice to have.

But also said that it's basically irrelevant. Hence my confusion.
