Energy density is ~8 times higher than in 2008 at 1/10th the price. That's more progress than we've made in single-core performance in the same timeframe. Sour

Did you mean 'more progress'?

Any idea why utiliy-scale is so much more expensive than automotive?

  Fire control, temperature control, chemical safety systems, daily 2-3C (half hour to 20 minute) charge and discharge rates, industrial grid scale high voltage grid forming inverters. And finally, the auto-makers got to the front of the queue for raw materials before prices spiked (and the ones that do both just take the profit). Expect more consistent prices in Q3 2023 once the end of the lithium bubble works its way through the system.

That has to be an astroturfer that posted that comment.
