Because we used to be a high trust society where degenrate gamblers wouldnt mess with scientific equipment to rip each other off
lol, the OP is such a classic HN take. "Why doesn't society simply absorb a negative externality created by gambling and add high cost redundancy layers that are otherwise useless" - Not every problem is technical.
I'm sorry, what is this "high trust" society of which you speak?
Counterpoint, why are we measuring temperature on what is basically a giant radiator?
I hear what you're saying man, but honestly it's a sensor. Sensors can fail all the time even without deliberate tampering. It doesn't seem to really make sense to have a single one in a single location. Besides for clarity, my question was more why was the market referenced on a single sensor rather than on multiple sensors?
