Re: NHSX devs apparently superior to Google devs
That's a silly statement. Without knowing exactly who is involved, you can't possibly know whether the UK dev team or Google happen to have some academic genious who's come up with a brilliant new mathematical model to do the calculations.
I'm not saying either side HAS done this, but assuming that Google must be able to do better is not only disingenuous but is disparaging of all other research groups. After all, we already have evidence that Google buy up companies who have good ideas (and patented IP) that Google didn't invent. They'd also invented stuff too of course.
