I'd also emphasize that they have 9 years on their runway (pun intended) until they plan to have it operational for consumers. That's a long time for battery tech to get better.

Not necessarily. Don't be fooled by the improvements in semiconductors and storage in the last decades: not everything doubles every 2 years. Battery specific energy seems to grow at around 5% per annum, doubling only every 14 years.
