made it out to be. That post is over 15 years old at this point, which goes to the very point of the posted article - C++ has (subjective opinion here) improved a lot in that time.
No idea what his current opinion on C++ is. Personally I'd rather there was no C++ or Rust in the Linux kernel. IMHO it would be significantly less of a cognitive burden to convert the entire kernel gradually to C++ than Rust.
But I would necessarily hold a man to opinions he held 15 years ago when the landscape has changed so much in that time. Rust was only born the previous year (2006) and not championed by Mozilla until 2009. Yet here we are and there is support in the official kernel for it anyway, whereas C++? Not so much.
