Python will still be around, but how popular it'll be is an open question. For example, Pascal or Perl were huge in their prime, and while they continue to stick around, the torch has been passed on.

Sure, but if Julia relegates Python to a niche and Rust does the same thing to C, they're still the same kind of approach to programming, and not some high level, mostly automated thing. They don't fundamentally change how people program.

When you write idiomatic Julia ... not C in a Julia syntax, but actually leverage the native power of Julia, yeah, you write code differently.

Same with idiomatic Python or Lisp circa 1960.
