In my 20s I worried about losing my intellectual abilities in my 40s and 50s What you really just lose is patience for BS :) Sure, yeah, you lose 10% of your raw intellect if you stay healthy[1]. You probably more than make up for it in experience and wisdom. But hell the thing that demotivates me is the recycled insanity of large organizations, egotistical tech executives, hype cycles, and all the other BS. Eventual…
So. Much. This.
I'm an "older developer" as well and the one and only thing that gets in my way of learning new things is the amount of useless information in the documentation and code.
