8GB is just too low and was too low in 2020. It gets shared with GPU and once you swap you decrease lifespan of a soldered SSD. It’s okay for light use but let’s not kid ourselves that even if it was passable in 2020 it would be enough for much longer.
It got bashed for low RAM by everyone except mainstream tech „reviewers”. Tech media are glorified advertisements these days so the only thing that happened between then and now is that they switched from selling you that new shiny M1 MacBook to selling you that new shiny OpenAI model.
I’m not going to bash M1 MacBook Air. It’s awesome, the CPU was ahead of time and I knew it would last me years. That’s why I got 16GB one.
