   yeah, at some point memory footprint becomes an architectural constraint again, not just a number you throw more hardware at.

      The memory capacity wall has been coming at us at high speed in plain sight for decades. We've been ignoring it.

         How so? Memory bandwidth and capacity has been steadily increasing. On desktop for example, 10 years ago an i7-5960X was the absolute top of the line and it had a limit of 64GB, with most motherboards in practice being limited to 32-48GB, and this was an unthinkable amount of RAM at the time for desktop. Now the top end desktop chips support 192-256GB, and a year ago (before the RAM price spike) you could realistically buy that much if you wanted for a reasonable price.

            The corresponding thread count has increased by much more than 4x.

               Has it? The i7-5960X was 8C/16T, Ryzen 9 9950X (and variants) are 16C/32T. Even the Threadripper PRO 9000 WX is 96C/192T and supports a staggering 2TB of RAM.
