Imagine you find yourself making TC $1M+ a year owning some beloved piece of software.
Do you A) tell your management hey it's absolutely perfect as is, let's just chill, leave it alone and let the money roll in. Or B) tell management about the need for whatever new hotness and you're going to get it implemented ahead of schedule and under budget. And then you do! Oh but the software is objectively worse because it was already perfect.
It's pretty clear what the overwhelmingly popular answer is to that question.
