Re: The conference was interesting
Hancock was talking bollocks. Apple say they haven't even been contacted, and it turns out that NHSX haven't even done any testing of the Apple/Google system at all.
As many people have pointed out, the technique itself has quite large unavoidable errors.
Being charitable, someone probably told Hancock that the technique is quite imprecise, and he simply doesn't understand that the NHSX app is using the same technique.
Would be very hard to explain that to him though as he has no understanding of what "2m" or "social distancing" looks like anyway.
