People still complain about PHP saying how it is not secure at all, how shitty of a language it is, and so on, because they are stuck at PHP 5. Everyone should just start from PHP 8.
I have no clue what the future brings for PHP, but PHP 8 is definitely a good start, and we should put PHP 5 to rest.
PHP 10 might not be that different from PHP 8 for all I know.
We do not know if there will be "constant change". Out of curiosity, what programming language do you use that you also love?
FWIW, if by "constant change" you mean improvements or bug fixes, then I do not see why we should not have those. I do not even mind breaking backwards compatibility if the reasons for breaking justifies it, but it has to be a really good reason.
It gets updated but breaking changes are not that many and always well justified. Most breaking changes I've seen the past decade only broke if your code was already bad relying on non standard ways of using language features. There are tools that help with migration.
People also hate how _slowly_ Python moves and complained forever about that. They also complained forever during the many years of 5.x PHP releases that PHP was moving too slow. It was only after Facebook forked first the runtime (HHVM) and the language (Hacklang) and showed how fast and advanced PHP could be made that the PHP team started accelerating. Which I think has been a boon to the community. This is all given away for free as open-source after all.
