Nuclear has never been profitable without massive government subsidies and guarantees, and Google Kairos too will either manage to collect those or lose money.
It’s unclear how Google and Kairos set up the deal — whether the former is providing direct funding or if it just promised to buy the power that the latter generates when its reactors are up and running. Nevertheless, Kairos has already passed several milestones, making it one of the more promising startups in the field of nuclear energy.
I guarantee you, they are shouldering on none of the risk (like the Chinese and French at Hinkley Point), and this startup will be going down.
That doesn’t mean all fact checks are bullshit, just that fact checkers are people with jobs and opinions too.
