Energy Usage
The energy consumption required for training these models is a huge problem, but that’s a sunk cost. The decision to use AI involves weighing the environmental costs against the benefits. It is not my place to make this tradeoff for every user. Each individual or organization must evaluate whether the productivity gains and other advantages justify the energy expenditure.

Usage and Practicality
Users are going to use LLMs to help them use a terminal emulator whether support is built in or not. By building it in, the tool is more useful for these users. LLMs make mistakes all the time, but in my experience the quality is good enough to be useful.
