Lawyer is a very bad analogy. Most legal work are boilerplate, the money you pay is the accountability against screwing up.its not sheer speed nor energy... more about cost...
if lawyers charge $500/hr of billable work, but I can go on hyperbolic.xyz and use Llama 3.3 model for 20 cents per million token, guess which one most people are going to use?
The same is true in many industries, accounting, general aviation, medicine...
