I loath having 80 char limits. Nothing worse than you end up 3 characters over on a condition and need to try format it nicely across 2 lines. More often it’s less readable splitting it than just having it on 1 line.

If 80 char is a warning it’s ok. Because obviously if every line is super long that’s not readable either. Needs to be a balance.

I feel like it hinders readability. Sometimes the end of a line isn't that important and can mostly be inferred from the start of the line or only occasionally needs to be inspected, meanwhile being able to see more of the whole file on screen at once can be really beneficial.

My workplace has a C++ character limit of 80. A lot of people complain but I can have three code windows side-by-side plus a source tree so I think it's great.
