This is extremely misleading and not very useful. It makes little sense to use pricing per GB during decades when RAM was at most in MBs. In that case, why not talk about price per TB or PB? Then the line will look pretty much flat and horizontal.

The line would look the exact same if you switched it to price per PB. Only the labels on the y-axis would change.
