> directly reduces my billable hours

Think about the adversaries using LLMs to generate ever-increasing preponderous walls of text that are mostly sycophantic and subtly legally blonde. If every adversary to my law firm generates 250% more text than before, our billable hours will balloon accordingly to the time it takes junior partners to read it all, digest it, redact, whatever. In fact, speaking of redacting, perhaps billable hours increase as you proofread your own LLM output. Regardless, LLMs should empower even criminal defendants to become quasi-eloquent and "type" 1,000wpm. It would seem that "reduces billable hours" is a naïve and premature prediction.
