Reaction time
In the US, using a cord like this will either be harmless or create effectively a dead short. Typical breakers will catch the latter but it will take tenths of a second for a breaker to react in which time the electricity could kill someone.
Depending on circuit conditions a GFCI might intervene as well, they’re typically faster at reacting (needing a few milliseconds) but for a cable designed to handle full residential power, it’s still enough to kill a person in that small window of time
From a technology standpoint, nothing is stopping them. From a business standpoint: hubris.
To put time and effort into creating traditional logic based algorithms to compensate for this generic math model would be to admit what mathematicians and scientists have known for centuries. That models are good at finding patterns but they do not explain why a relationship exists (if it exists at all). The technology is fundamentally flawed for the use cases that OpenAI is trying to claim it can be used in, and programming around it would be to acknowledge that.
