## The $600 hour data entry job
A Harvard Law graduate's first assignment was manually checking signature lines across 18 documents. The law firm billed the client over $600 per hour for this routine task.

> The firm billed the client over $600 an hour for me to use all of my schooling and education to accomplish this task.
## AI enters the legal scene
Harvey and Legora launched less than five years ago and now dominate the AI legal market with valuations of $15 billion and $5.6 billion respectively, acting more like tech companies than law firms.
## Big Law firms scramble to adapt
Law firms are hiring top engineers and transforming into tech companies behind the scenes. Legal tech, once considered impossible to sell, is now the hottest thing in Silicon Valley.

> It used to be a running joke that selling legal tech was near-impossible because law partners have no incentive to maximize efficiency.
## Star lawyers are leaving
Top lawyers no longer need Big Law's infrastructure and are launching their own tech-driven firms. Chris Kercher leaving Quinn Emanuel to start a small firm is no longer an outlier.

> Lawyers are realizing they no longer need a big firm's infrastructure or training model, and star players are walking out of top firms.
## Legal services will democratize
AI will expand access to high-quality legal work beyond wealthy clients, flatten Big Law's influence, and create new career paths for young attorneys outside hierarchical firms.

> A decade from now, many BigLaw firms will be skeletons of themselves. Along the way, access to high-quality legal will expand dramatically.
## Key takeaway

AI is forcing law firms to abandon their traditional model of billing junior associates at premium rates for routine work, opening the profession to more people and changing how lawyers build careers.
