Selling your data would be stupid, because they make money with the fact that they have data about you nobody else has. Selling it would completely break their business model.

There are a lot of YouTubers just playing with them, but I think Jim Browning is the only one actually taking them down.

Reducing the attack surface by not using well established and battle tested crates but reinventing the wheel inside this closed source project 🤣

All calculators that are listed in the article as following weak juxtaposition would interpreted it that way.

Did you read the blog post? I also quoted the exact same thing.

"when in doubt" is a bit broad but left to right is a great default for operations with the same priority. There is actually a way to calculate in any order if divisions are converted to multiplications (by using the reciprocal value) and subtractions are converted to additions (by negating the value) that requires at least a little bit of math knowledge and experience so it's typically not taught until later to prevent even more confusion.

For example this: 6 / 2 * 3 can also be rewritten as 6 * 2⁻¹ * 3 and because multiplication is commutative you can now do it in any order for example like 3 * 6 * 2⁻¹

You can also "rearrange" the order without changing the meaning if you move the correct operation (left to the number) with it (should only be done with explicit multiplication)

6 / 2 * 3 into 6 * 3 / 2 (note that I moved the division with the 2)

You can even bring the two to the front. Just remember that left to the six is an "imaginary" (don't quote me ^^) multiplication. And because we can't just move "/2" to the beginning we have to insert a one (empty product - check Wikipedia) like so:

1 / 2 * 6 * 3

This also works for addition and subtraction

7 + 8 - 5

You can move them around if you take the operation left to the number with it. With addition the "imaginary" operation at the beginning is a plus sign and the implicit number you use is zero (empty sum - check Wikipedia)

8 - 5 + 7

or like this

0 - 5 + 8 + 7

because with negative numbers you can use the minus sign to indicate negative numbers you can even drop the leading zero like this

-5 + 8 + 7

That's not really possible with multiplication because "/2" is not a valid notation for "1/2"

Did you read the blog post?

You also probably help with edge cases. All it needs for them is to shift (and or rotate) the images slightly when presented to other people to get more accurate results.

Not only that but there is very likely a huge beauty bias in the training sets.

Wow that was fast I just edited my previous comment and you probably mean "1 and prime numbers" by numberphile with james grime.
