@stefano I find a similar thing happening more often with my colleagues too.
I think the luck of knowing can be fine, after all I didn't know what I know now and I keep leaning new things. I find the real problem is the lack of willingness or incentives to learn new things.
And I really don't understand why people that call themselves developers would not want to learn or how to change that in them (I doubt anyone but them could really change that).
Ignoring the vibe coders aspect because well vibe coders.
