Exactly. In the next few years, entry-level hardware will not be advancing beyond 16GB. And anything beyond 32GB will remain decidedly high-end.
And that's for laptops with unified memory. In the desktop space, 8GB discrete GPUs are going to be sticking around for a very long time.
I guess we'll find out! I bet all the vendors who supply RAM are looking at the current shortages and thinking "well, it's a shame we could never manufacture more RAM than we currently do."
