I appreciate the intent behind that sentence, and the problem is that is written (or said) by people who don't understand coding.
Syntax was never the hard part. Code syntax is a set of rules that you can teach a machine and it's "easy" enough for an LLM to grasp it. The problem here is that this phrase does a "code = syntax" but ignoring all the difficult things that actually are in the code. Architecture, design, tradeoffs, translation of vague requirements into concrete software components...
All of those things are terribly hard, and the reason why many LLM-first coding projects get abandoned at 70% and then companies need to hire a Software Development consultancy to mop up their mess.
