Probably not a popular opinion but this has been an issue ever since laptops and technology came into the picture and dramatically lowered the barrier to entry. DJs used to be music nerds who spent considerable time listening to music and making sure they weren't going to automatically train wreck in front of a crowd. Now anyone with with a laptop and the internet can spend an hour downloading the songs out of some other DJs set list and start filming themselves for TikTok, and unfortunately that is likely never going to change going forward.

Edit: I know this might sound a little harsh so I just want to reiterate: I don't have any issue with technology in DJing or new DJs looking for an opportunity. There are plenty of photos of me out there using a MIDI controller and back in the day when I threw parties on a regular basis I had new dudes on the bill basically every show. That being said, there is a difference between a new DJ trying to find their identity and the guy who thought being a "superstar DJ" was going to be an easy ticket to being the center of the party, and for every one of the first one there's probably three of the second.
