Glad I'm not the only one who noticed there is a weekly (or more) post on what Fourier transform is.

It's really getting in the way of all the daily AI opinion pieces I come here to read.

More seriously, there are tens of thousands of people who come to HN. If Fourier stuff gets upvoted, it's because people find it informative. I happen to know the theory, but I wouldn't gatekeep.
