> Today my "coding" sessions often enough begin with real life problems

intuition is that your sessions consists of 10% of domain related reasoning, and 90% of code plumbing. Those 90% could be moved to cheap and efficient specialized and focused model.

Possibly! It's just hard to reason about from the outside. When does the model benefit from all the ambient knowledge? Idk.

Regardless, it's fairly obvious to me that none of what I do now will require "frontier models" for much longer. Models are getting better more quickly than my problems are getting harder.
