The end of that chart is in 2020 and in the interim the DRAM makers have been thumped for price fixing again, causing a non-trivial short-term reduction in price. But if this is the "real" price then it has declined from ~$10/GB in 2012 to, let's say, $1/GB now, a factor of 10 in twelve years. By way of comparison, between 1995 and 2005 (ten years, not twelve) it fell by a factor of something like 700. You can say the free lunch is still there, but it's gone from a buffet to a stick of celery.
