A dev myself, I see any new tech that looks like something I've seen before, but different from the immediately previous, as the natural young revolt against the old (5 years older), in an attempt to be important (i.e., e.g. being paid). Sometimes I'm younger than last year too, and I throw away a lot of what I learned. I should strive for wisdom: knowing what should come and what should go.
