"What I'm getting at is, I don't know why you need to update anything"
Shocking advice. There is a huge amount to learn. Any developer coming from the 1990s needs to re-learn all their technologies or they are going to have a very stressful time delivering anything appealing to users expectations in 2016.
"Since the stuff you already know still works, there's not much need to use anything else"
This kind of mentality leads to becoming deadwood and unemployment. Developers must keep learning especially with the rate of change of technology over the past 5 or so years.
