Of course it still matters. What else would both teach programmers that nice languages exist, and that OOP leads to a nondeterministic spaghetticode hellscape?

Of course it still matters. What else would both teach programmers that nice languages exist, and that OOP leads to a nondeterministic spaghetticode hellscape? ;) (I once spent an entire month debugging a transient login issue (session loss bug) on a million-line RoR app. Most of the bug ended up being something which merged a HashWithIndifferentAccess with a regular Hash, and key overwrite was nondeterministic. This type of bug is doubly impossible in something like Elixir- both since it is data-focused and not inheritance-focused, and because it is immutable.)
