Often whenever someone quotes how many years/decades of experience they have, I then begin to wonder if they have become complacent and/or adverse to learning, improvements, and change.
That's a lot of negative shit to be assuming based on a cursory comment. If someone was averse to change, they probably couldn't be bothered to stick with anything because just about everything changes. I know I'd rather seek advice from an experienced specialist rather than a rando person with some limited experience.
