How much will it cost to rewrite everything? What were they suppose to choose in the 70s? Do you think that all of the people still using IBM and running legacy code are dumb or just maybe they did a cost benefit analysis and decided they didn’t need to rewrite everything in Node and React?
Maybe you should ask why some sector that "fear" failures more than anything else (banks, aviations) are still trapped into these systems while everyone else is not.
This is exactly related to what I was saying before.
