I think nerdy stuff is attractive to people on the autism spectrum, and while people on the spectrum tend to like consistency, they also have trouble recognizing social norms, let alone following them. So some act that is in large part (from other people’s perspective, at least) a deviation from social norms isn’t that much of a problem to them. And why wouldn’t trans people prefer to be in spaces where people don’t care how they’re living their life? Now, add on that exposure tends to normalize social experiences, and people on the spectrum are already weird in their own way, and the neurotypical people in those nerdy spaces are already used to dealing with weird people. Adding a different flavor of weird isn’t that much of a stretch.
Or, to put it another way,

What you’re saying is mostly right, and in a practical sense is right, as well, but not as much from a technical sense. This is the specific block that is problematic.
This is generally correct, per cycle. Overall, it really depends. The problem is, the x86 architecture does okay as long as it’s kept busy and the work to be performed is predictable (for the purposes of look-ahead and parallelization). This is why it’s great for those mathematical calculations you referred to, and why GPUs took over - they’re massively better performers on tasks that can be parallelized such as math calculations and graphics rendering. Beyond that, the ARM use case has been tuned to low power environments, which means the computing does poorly in environments that need a lot of calculations because, in general, more computing requires more power (or the same power with more efficient hardware, and now we’re talking about generational chip design differences). Now, couple that with the massive amount of money spent to make x86 what it is, and the relatively lower amounts that RISC and ARM received, and the gap gets wider.
Now, as I started with, even a basic x86 computer running at mostly idle is going to have pretty low power consumption, dollar-wise. Compare that to the power draw on a new router, or even a newer low-power mini PC, and your ROI is not going to indicate the need for that purchase if you have the hardware just sitting around idle. And it will still perform better than a raspberry pi configured to act as a router if your bandwidth is above about 250 mbps, if I remember correctly (and something like 120 mbps for the v4 and earlier generations).
