> 2) When optimizing your code, you no longer refactor to improve speed or code maintainability, but mainly to reduce the fees charged when executing. Solidity even has a "price sheet" of fees for operations like addition, subtraction or allocating memory. This new way of thinking can seem strange to experienced devs because of all the easy fixes you plainly see that have to be left in the code base. Counter-intuitive.

That makes me think of the game Shenzhen I/O: each component cost money, each executed line of code draw power, you have to optimize your circuit to match your assigned power and price goals.
