@ramsey i am not a serious php developer but have been using several amazing php projects (#mediawiki, #moodle etc etc). What i notice is a certain stagnation, domain specific silos, priority in safeguarding existing usage rather than inventing the future (which is what creates senior developer opportunities).
I might be just talking nonsense but maybe the emerging fediverse (not just the social media variety like #kbin but broader federation) will rejuvenate things given PHP is web-native.
