From the get off my lawn crowd (60) I don't mind being pushed out mostly because the work doesn't look that interesting at this point. I managed for 38 years with nothing in the way of languages (C, C++ when it became available, a whole bunch of assembly languages for exotic processors) by modern standards. Most of the heavy lifting in the workstation and high end embedded world was algorithmic.
Within 10 years here I had encountered more than 10 different CPU architectures. I've lost count now, but it is probably at least a dozen. The same goes for OSes.
All they are is dust in the wind.
