If you lived before the invention of cars, and if when they were invented, marketers all said "these will be able to fly soon" (which of course, we know now wouldn't have been true), you would be underwhelmed? You wouldn't think it was extremely transformative technology?
Maybe hype is overly beneficial to them but if you promise me 1500 and I get 1100 then I will underwhelmed.
And especially around LLM marketing hype is fairly extreme.
