Yeah, I've noticed that younger programmers started talking down to me like my experience is worthless. Then they ask me to debug their code for them.
The frustrating part is that, when I interview, my experience in now-obsolete languages has a value of $0. My skill for understanding business requirements and debugging is mostly transferable, but that doesn't seem to be valued. I understand valuing my experience in older languages at a discount, but I don't understand why it gets a value of zero or negative.
I never saw the point of hackathons, because I'm interested in projects that take more than a couple of days to finish. You can do "Uber for X" in a weekend, but not something substantial or truly original.
