Is it? Legal is rarely a genuine war of attrition and delays are the norm. AI is years/decades away from not needing humans in the loop verifying output, legal more than most. Correctness is more important than speed. Main skill is doc search but most cases easily fit in modern contexts.

So I don't think legal in particular needs the fastest/bestest compute.
