“This finding places the theorem among other probability puzzles and paradoxes… where using the idea of infinite resources gives results that don’t match up with what we get when we consider the constraints of our universe,”
No shit. The “infinite monkey theorem” doesn’t hold true witout infinity.
The result is something every interested high school student could come up with.
Hand written assembly is pretty common in video, no matter what they say. All modern video codecs have hand written assembly for all modern SIMD extensions, even on ARM. They didn’t say anything about where these numbers come from. Likely compared against unoptimized C code. There will never be a case where having AVX-512 will give you that kind of speedup, because there will be fallbacks for more common extensions.
