Yeah, light emitting diodes don't work like traditional incandescents. I suppose you could say that a filament bulb is a controlled fire, at the most simplistic and basic level, but that's a misrepresentation of what's really happening. The filament heats up to a very high temperature, causing it to glow and emit light. This process is known as incandescence, and it involves heating a material until it emits light, rather than burning or combustion, which would involve a chemical reaction with oxygen to produce fire. The bulb is filled with an inert gas or a vacuum to prevent the filament from burning up due to oxidation.

The problem with your examples is that they do affect the user's ability to use the tech in question, and the same can't be said for HTTP. If there isn't a clear benefit to knowing something, then making it a requirement is just an artificial gate and an unnecessary burden. For example, pharmacists don't withhold your prescriptions because you don't understand a drug's mechanism of action, but they do make sure you understand the risks and any drug interactions. Airlines don't force you to learn how their planes create lift, but they do educate you on what to do in an emergency. I don't see why tech should be any different from those 2.
