Use of classes or functions discussion

[Mekire]

This video is quite popular. I think it tells everything

I actually quite dislike that video.  He comes off pretty damn condescending.  Yes you shouldn't write a class when you don't need one which are the examples he shows.  But if you do need one you should use one.

His examples deal with a lot of cases where people write place holders for future potential use cases.  So yes, don't overthink and write a bunch of useless code for the ostensible reason of "future proofing" but nonetheless, if you need encapsulated state with associated methods, you should be writing classes.
