> I have always found "not knowing" a programming language to be such a fascinating failure mode for professional software engineers This is how you wind up with code riddled with vulnerabilities and anti-patterns, with extremely bad performance imo It's so easy to say "I know Java and C# is basically the same" and then wind up using built ins that are deprecated, using libraries that contain vulnerabilities, or whatever other mistakes Maybe that's "good enough" for your usecases, but I've never found that it's a good idea to just assume I can switch languages for anything reasonably complex without some growing pains.
