A given group of people are not a monolith. While we do share a lot of similarities, we also all have the potential to be a little different from one another.
I hope you get a chance to find someone that will allow you to be open like that again. Sharing those emotions and having someone their to empathetically receive them is one of the most gratifying things as a human.
Actually the National Electric Code (NEC) limits loads for 15 Aac receptacles to 12 Aac, and for 20 Aac receptacles 16 Aac iirc because those are the breaker ratings and you size those at 125% of the load (conversely, 1/125% = 80% where loads should be 80% of the break ratings).
So with a 15 Aac outlet and a 1000 Wac load at minimum 95% power factor, you’re drawing 8.8 Aac which is ~73% of the capacity of the outlet (8.8/12). For a 20 Aac outlet, 8.8 Aac is ~55%% capacity (8.8/16).
Nonetheless, you’re totally right. We’re not approaching the limit of the technology unlike electric car chargers.
