You are correct.  I was wrong.  Let me fix that with a two word edit:

SSD life has increased substantially in the 3-4 year period since.

Overall useful life of an SSD (the whole device) has continued to increase
substantially thanks to better wear leveling controllers and RAISE, even though
individual flash cell life has continued to decrease as process geometries
continue to decrease.
