I second the above.
I don't remember the specs of my first desktop, but my first upgrade had 502 mb ram (yes, that's the way I remember it, not 512). I'm pretty young.
At some point computer software and operating systems progress past the capabilites of hardware from a few years ago.
There's still a thousand and one uses for 8gb ram or even 4gb ram machines, but you don't drop $800 on a new model with that little ram, and throttled ssd to boot. If you need a media consumption device or a chidushei torah word processor, find something cheaper.
I don't have much apple experience, so maybe I'm wrong and there's use for a MacBook with 8gb. Even so, go buy the m1 model for $150 cheaper.
