I don't want to sound like a prick, but this is generally what people mean when they say "things are moving very fast due to amount of investments". 6 months old beliefs can be scrapped due to new models, research and etc.
Where "etc." includes lots of engineers who are polishing up the frontend to the model which translates text to tokens and vice versa, so that well-known demonstrations of the lack of reasoning in the model cannot be surfaced as easily as before? What reason is there to believe that the generated output, while often impressive, is based on something that resembles understanding, something that can be relied on?
