Different things work for different people, and at different stages too.
Many methods are small variations of roughly the same thing just with a different name, and many principles of ALG are valid. But:
I don't buy the core idea of natural learning only, and I say it by experience. We idealize massively how kids learn; just because they don't complain so loudly it doesn't mean that languages are not hard for them – some kids actually struggle a lot, and they progress really, really, really slowly.
Genuine directed study – specially below B2 – is pretty damn useful, and there is a ton of evidence of it.
