Why doesn’t Google sell these?
They could still be renting them out.

Interesting times ahead with a number of chip makers now vying for this market. TPUs are a mature chip now which gives some strong advantage. At the same time as the TPU announcement, they also mentioned they'll be deploying Cerebras systems as well.
Then again, if they can provide competition to Nvidia, it may force Nvidia to lower prices across the board.
And even if Google sold them, they probably won't sell any affordable ones. Nvidia sells DGX Spark, but who can afford to buy them?
