I think it is mostly accurate to say that the cost of execution has dropped to zero.

In this new world, the ability to say "no" is more important than ever. It has never been so easy to burn time, money and energy. The fact that you can try anything now can be modeled as a disadvantage. The space of possible solutions got a lot bigger. Unless you have good taste you could wander and get lost very quickly in this vast new expanse. A true expert that has more paths to work with can arrive at higher quality solutions faster. A novice will get into trouble faster.

It often takes 10k hours suffering through an idea with a live customer before we deeply learn why something is a bad/good approach. None of this painful wisdom is available in the models. You can easily change the mind of ChatGPT with a single adjective. You cannot so easily persuade the person who has successfully cast the ring into the volcano already. They know what it actually feels like to get there.
