> All that being said, if you've been working since the 2000s, you've got nearly a 20 year head-start on me, so perhaps it makes sense for me to be a bit more worried.

Yea, that's mostly why I get hired. Experience gives people a certain intuition on what kind of solutions work for which cases.

And when you've been working long enough, you don't (hopefully) feel the need to do cool bleeding edge shit at work, you just want the work code to ... work. You pick the simplest and most boring solution possible so you can clock out at 1600 and not think about services crashing because the newfangled thingamageek coded with the latest language du jour failed because of an edge case nobody has seen before.
