Sorry for quoting out of context, but I also do that. The reasoning goes: when I have to do something and it’s clear how to do it, there is no need for “the other way”. I perceive it as changing routes daily just for novelty, against boredom. Old tools have nuances, so do new ones. But the work is done by me + tools, so the best combination is me + what I know to the bone.
Is this bad for a developer? Does that stress colleagues often? No catch, just asking.
And I do learn ofc, after some “it sucks too much” threshold. But years of early development taught me to raise that bar much higher than my procrastination pikes, otherwise I end up in a loop of jumping tech and never get satisfied.
Edit: to make it clear, other described “traits” I do not have.
