We all know the tech is out of date at its core, but I don’t think it’s fair when people say they’re holding PHP back when there is an active effort to keep things compatible.
In general, the WordPress community is _slow_ and plugin authors and users definitely do not keep up at the same pace at the rest of the community using more modern frameworks. They tend to have written worse code in general, which are proportionately more impacted by deprecations and error promotions where the code wasn't using best practices.
The PHP internals maintainers hear complaints from people in the WordPress space saying "whoa you're making too many breaking changes too fast, I can't keep up", meanwhile having the developers of modern frameworks getting impatient, wanting all the new features to save them time in writing new code.
If PHP didn't have all these legacy projects still in use, deprecations/strictness changes could move at a faster pace.
After some arguing with the company that is payed to manage their IT environment she got them to finally update the php version and now the server is running 8.1.
I was glad that at least wp was up to date. Current wp running on quite old php version and exactly nothing broke with the update.
I was positively surprised. Would have expected more problems from my experience with other projects in other languages.
