I seem to see a lot of advice on the all knowing tinternet that we can more or less ignore future subjunctive for conversation purposes as the present subjunctive is used in its place… I know we do this for other tenses etc…
I had a row with chatgpt about this subject 
Oh, this is a commonly used tense in Portuguese, so I would say you can’t really avoid it. Even if you try to use other alternatives yourself as much as possible, other people will still use it and you’ll want to understand them 
I’d say almost the opposite! Just tackling this now in my coursebook and wondering how on earth I got this far without it, seems to be used so much, so many common phrases and situations. The units here have really helped too.
Claro que não!
