Once something is mainstream and non-perishable, odds of it going away go down and it's foreseeable that it will be around for at least as long as it's already been around.
This effect is super strong in tech, for base technologies, with lots of integrations, especially around enterprise/governmental systems (which don't get changed unless someone makes a strong business case why the change makes more money) and consumer hardware (which tends to linger for aeons since it's so distributed).
