I have an M2 MacBook Air with 8GB of RAM that I bought three and half years ago. For browsing the web, listening to music, watching TV and movies, using Gmail, Google Sheets, Google Docs, etc., it's still perfectly fine.
OTOH, for my development Mac, I have 64GB of RAM. (Though 32GB would probably be fine.)
