I think before taking anyone's advice on learning a language, you should ask a native speaker of their target language to give you an honest opinion of their progress. So in in his case, we need an Italian to tell us how good (or bad) his Italian is.

Personally I think the piece of advice of using and SRS and a word frequency list isn't bad as a first step in a language, just to get that initial hit of vocabulary - so there he gets approval from me.

The rest of the video I disagree with. He suggests that you start engaging in conversation practice from day 1, but in my view that is an awful idea.

Even looking at the conversation clip he shared (18:20), all we see is him struggling to speak Italian and stuttering and eventually spitting out some (probably very wrong) words. How much is is really learning during those seconds? Would he not learn more if he spent those same seconds consuming Italian media?
