Both of those things came together in the mid/late 90's and gave birth the the modern day tech career. Since then the modern day tech career has changed very little if at all.
Anything before that was not even comparable. Mostly academic researchers and labs.
Yes, we had cars that existed in the 20's and 30s, but listening to those "oldheads" about what worked for them at that time if you were in the post-WW2 auto boom in the US wouldn't make sense. See also: aerospace pre/post jet propulsion.
My time outside of work has changed substantially however.
Stereotyping is fine as long as it’s understood to be fundamentally wrong and inefficient, and when applied to people cruel.
My point was: Saying "this is what worked for me finding a job in the 80's/90's" isn't necessarily great advice, because it's not the 80's or 90's. If an oldhead says "this is what worked for me last year" sounds like he's giving useful advice.
Put succinctly: Oldhead advice is great when it's relevant, but oldheads need to understand that not all their war stories are useful. Feels like an extremely reasonable take, but strawman me some more if that's what gets you off.
Signed- An oldhead!
We still didn't have the internet in our houses then, though.
