If you see the difference between a 7B model and a 70B model, its only slightly impressive. a 70B and a 400B model is almost unnoticeable. Does going from 400B to 2T do anything?
Every layer like using python to calculate a result, or using chain of thought, destroys the purity. It works great for Strawberries, but not great for developing an aircraft. Aircraft will still need to be developed in parts, even with a 100T model.
When you see things like "By 20xx", no, we already hit it. Improvements you see are mere application layers.
