If you're (1) doing something basic and (2) don't care about correctness or quality or reliability and (3) don't need to change or maintain it, then by all means, use it. It's literally no different than copying off StackOverflow (and probably being generated from it.)
If you aren't an engineer, I get why you think it's magic. Everything is magic when you don't understand how it works.
Nobody thought the iPhone was magic. It was an instant hit because the capabilities were immediate and obvious, and Apple had a long history of being able to execute.
If you find it useful, by all means, use it. But this is the new blockchain.
