One of the biggest reasons these misunderstandings are so frustrating is because you can't have reasonable discussion about the potential interesting applications of the tech. On some level copy writing may devolve into auto generating prompts for things like GPT with a few editors sanity checking the output (depending on level of quality), and I agree that a second opinion "check for tumors" use has a LOT of interesting applications (and several concerning ones such as over reliance on a model that will cause people who fall outside the bell curve to have even more trouble getting treatment).
All of this is a much more realistic real world use case RIGHT NOW, but instead we've got people fantasizing about how close we are to GAI and ignoring shortcomings to shoehorn it into their preferred solution.
Open AI ESPECIALLY reinforces this by being very selective with their results and they way they frame things. I became aware of this as a huge dota fan for over a decade when they did their games there. And while it was very very interesting and put up some impressive results, the framing of those results does NOT portray the reality.
This sort of fusion of different capabilities is likely to produce something that feels similar to AGI in certain circumstances. It is certainly a lot more capable than things that came before for mundane recognition tasks.
Now of course there are areas it would perform very badly, but in unimportant domains on trivial but large predictable datasets it could perform far better than humans would for example (just to take one example on identifying tumours or other patterns in images, this sort of AI would probably be a massively helpful assistant allowing a radiologist to review an order of magnitude more cases if given the right training).
