That means it's catching cases where the doctor already thinks there's an issue

Compare with the Machine Learning exercise back in '17 I think that was attempting to identify cancers from photos, only to have their "AI" learn that photos with rulers in them were more likely to have cancers identified later (because they only used a ruler for lesions that were concerning to begin with before taking the photo.):

In a new study, scientists find another reason why air pollution is bad for the brain — this time zeroing in on the effect it has on men’s brain health. The study examines the negative effect of fine particulate matter, also known as PM 2.5 pollution. You might know it as black carbon or “soot.”

A four-day week in the public sector would create up to half a million new jobs...

So, the private sector cannot do this, but the public sector (paid from taxes raised from the private sector) could.

What we in the UK need and want are less public sector tax-sponging employees, and more private sector tax-producing employees.

Comment $62.5bn, aye? (Score 1) 74

potential value of $62.5bn

That's the amount said waste is likely to be worth after it's been collected, transported to processing, actually being processed, along with other steps along the way.

The problem, that the people demanding this happen ignore, is the cost of that collecting, transporting and processing, which is likely to be well in excess of that final $62.5bn.

Which is why people must be forced into doing this collecting, transporting and processing. If it were profitable, people wouldn't need any encouragement.

Which shows that far from saving resources, the whole process is actually going to consume more resources - the complete opposite of what the people proposing this happens seem to indicate that they want.

*To generate secrets consistently even if you scan your DiceKey sideways or rotated up-side down, our software rotates your DiceKey to a canonical orientation before deriving secrets from it.

I couldn't, easily, find out how they canonicalise the orientation however, so that might actually reduce it by more than that last 4^1.
