This is a complicated, technical solution looking for a problem. Simple, asymmetrically-authenticated signals and felonies for the edge cases solve this problem without any futuristic computer wizardry.

Voltage dividers are still commonly used in MCU-laden designs, as are RC timing circuits. (The power supply sitting next to that MCU has a divider-based feedback loop, usually.) These possibly can't be learned from a wiki, but they can

Here's an idea: the airline could, you know, charge the price that the skiplagged flight would cost? If this is impacting their margins so dearly, they should incentivize for optimizing against it: nobody would ever take a skiplagged f

What numbers am I backing up? Should the price have remained the same? Or was 2022 not the highest year for USD inflation in 40 years (see: your own source.) Is a company only allowed to increase their prices at a rate pegged to monetary in

Ah right, the price should have remained the same despite the highest worldwide monetary inflation rates in the last 40 years. I can't imagine why would a company want to sell a product at a profit.

0 of these heavy UAVs will be able to operate in contested airspace. This is why you no longer see Bayraktar footage anymore, and they aren't even remotely as heavy.

This is called "HLS" (high-level synthesis) and exists. The emitted RTL is atrocious. Anything but the simplest programs will require way too much logic to implement with discrete components.

The one important thing missing from your query here is: How much current do you need? If you need, say, >100A, the possible architecture looks very different than ~1A or less.
