It's worth point out that on many microcontrollers (STM32's at least), configuring a pin as a "digital input" means that the signal is routed through a Schmitt trigger circuit that's built into the MCU.
This also means you'll want to ensure that any floating MCU pins are _not_ configured as digital inputs, as the Schmitt trigger circuit itself will waste power switching back and forth between high and low states constantly.
I don't think it's slop -- the sources are books and it doesn't read like slop -- but the sources are more worth reading. It's more like an undergrad trying to fill word count, without getting why this is interesting.
It's 100% AI-generated, including nonsense illustrations. And it's just so pointless too - there are many good, better-illustrated, and better-explained human articles about the same circuit.
I feel like I learned something from this about the high level need and attributes of the schmitt trigger design. But I'm sure I'd need to read the actual my sources to realize the physical design.
However the general idea of using hysteresis for signal conditioning seems transferrable to other non physical control systems. I suspect that people who think about what the article is saying rather than reflexively declaring it to be slop could learn something useful.

The "not gate inverter" is particularly nonsensical.

This is without a doubt slop.

Is the account that used to heavily push this domain, I'm surprised it hasn't made it to the banlist.
