I never really got it for the same reason. Not sure if my parents misworded it, or if I misinterpreted.

Growing up I always wrote off “it’s always in the last place you look” as just another random thing adults loved to just say all the time.

For context length, vram is important, you can’t break contexts across memory pools so it would be limited to maybe 16gb. With m series you can have a lot more space since ram/vram are the same, but its ram at apple prices. You can get a +24gb setup way cheaper than some nvidia server card though
