theory : age itself with regards to computing has nothing to do with how old you act (with regards to computing), the time you spent doing a specific thing is what grows that 'characteristic'.

Anecdote : i'm fairly young, but i've been involved with python long enough and traveled to enough pycons to be a bit jaded with regards to change within the language.

I'm fairly certain it's only due to the additional cognitive load that's thrust upon me when I must learn a new nuance to a skill that I already considered myself proficient at.

in other words : i'm resistant to change because i'm lazy, and because it (the language, and the way I did things previously) works for me. Both reasons are selfish and invalid, to a degree.
