Yeah for all of the criticism (rightly so), that AI gets. Breaking down any gatekeeping behind creating stuff on the internet has to be a net good.
I get where your sentiment is coming from, but when surveying the internet and world can no longer agree. If we define gatekeeping as the requirement to extend time and effort to gain some level of competence and understanding I'm totally fine with it. "creating stuff on the Internet" has been available to pretty much everyone for a long time, and the value of their product when the creation is easy & free is also easy.
People learning how to do things is not gatekeeping. It seems that word has lost all meaning. This person still did not actually create anything.
If you have internet access, there was never any "gatekeeping". There have been free resources to learn web development for ages. Someone not wanting to put in the effort to learn to do something is not being "gatekept", they're just choosing not to learn to do something.
