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.
