The great war of tabs vs spaces

For the longest time there was a disagreement. It was about tabs vs spaces. Developers argued in threads and pull requests. No conclusion to what was better.

I jokingly always said ”one tab and one space” and very few laughed. That is how serious the ”war” was.

Then code completion, prettier and lint came along and the discussion ended.

I wonder what discussions we have today that will feel ancient in a couple of years time.

Micro-services? AI assisted coding? Type in JavaScript? The cloud?
