Gate-keeping is a strong word… It also implies that people on the other side of the gate learned something to get there.

20 years ago we were doing what we could manually, and learning the hard way. The tools have improved and by now do most of the heavy lifting for us. And better tools will come along to make things even easier/better. That’s just the way it works.

Compare self-hosting to doing your own mechanic work on a vehicle: there are a lot of tasks that most ppl would benefit from learning the diy way to do it, but there are dangers to car repair that will never go away, like proper car support with jacks, securing wheels correctly, etc.

It would be neglectful for the community to say nothing and send ppl off to get pwned.
