I get the sentiment, but "I don’t like magic" feels like a luxury belief.

Electricity is magic. TCP is magic. Browsers are hall-of-mirrors magic. You’ll never understand 1% of what Chromium does, and yet we all ship code on top of it every day without reading the source.

Drawing the line at React or LLMs feels arbitrary. The world keeps moving up the abstraction ladder because that’s how progress works; we stand on layers we don’t fully understand so we can build the next ones. And yes LLM outputs are probabilistic, but that's how random CSS rendering bugs felt to me before React took care of them

The cost isn’t magic; the cost is using magic you don’t document or operationalize.
