That's demonstrably false - I can run Safari or Chrome on my 8Gb M1 macbook air 24/7 without any issues.

In which universe? I can run up to 5 tabs well under an Atom netbook with 1GB and some hosts bloking file.

with 8GB and the Intel NUC own as a desktop (Alpine Linux XFCE), with UBo I can open dozens of tabs without blinking.

Currently running Spotify + VSCode + Chrome + Slack on 8GB. That's 4 browsers, and it's totally fine.
