Wolfram works with the full mathematical expression tree. It works very well in practice but the equality test is undecidable in general.
I ran into this issue once while trying to render the Mandelbrot set while learning Haskell. It defaulted to a rational type based on two bignum integers with unlimited precision.
With every Mandelbrot iteration* the integers doubled in size, producing exponential complexity. With 100 iterations this essentially means that the program never completes and even runs out of memory at some point.
The newbie-friendly feature turned out to be not so friendly.
* complex z_{n+1} = z_n^2 + c

I find that rather unfortunate. A math search engine that find sites with equivalent formulae (or segments) would be quite useful to me.
Of course, that can probably made to work with image alt tags containing latex code.

Unlike the former, I could also imagine the latter being produced by a Markov chain.

One example i see quite often is: "X has been widely criticized for Y", with no mention of either the critics or the argument.
I think fallacy 2 is the big one, and not just in the AI field.
Sometimes a simple lookup table (or some other 'dumb' model) works well on tasks that humans generally consider 'hard'.
How do these ToF systems deal with multiple sensors pointing at the same scene? I've seen it work with two ToF sensors, but haven't been able to find a good explanation for how it works.
Isn't the observer model explicitly built into NeRF architectures?

I find the general idea of treating differential equations as infinitely dimensional linear systems quite powerful. I was first introduced to the concept while studying quantum mechanics, but applications are everywhere.

I know quite a few idyllic places with lots of nature. None of them have fast internet.
If only there was a search engine that filtered for these criteria.
I really hate sites that send all content as html, but then hide it only to unhide it with JavaScript. It's getting quite common though. I wouldn't go as far as the OP and say no JS, but how about: don't use JS just because you can, use it to actually do something that makes the site more usable.
Some sites let the user provide a email address in order to allow password reset, but don't force it. I think this is a good practice.
