This constant outrage at every perceived slight is a recent phenomenon of the Facebook/Twitter decade and it is suffocating.
> Be kind. Don't be snarky. [...] When disagreeing, please reply to the argument instead of calling names. "That is idiotic; 1 + 1 is 2, not 3" can be shortened to "1 + 1 is 2, not 3."
"That is a question that a junior developer would ask" is not on the same level as "that is idiotic".
If you're asking after "hot new tech" it's probably because you haven't been around long enough to see how tragically wasteful the "hot new tech" treadmill is. The "30 year" comment manages to communicate that very directly.
Frankly, the OP said something rude. It's not a "perceived slight". It was unnecessary, offensive, and presumptuous. Why shouldn't they be called out on their behavior? Congratulations on your ability to ignore the first sentence, but that doesn't excuse OP.
