Lawyer has been a poor earning profession (for the education needed) for a while now. There are a few expensive lawyers who make a lot, but your typical lawyer is not highly paid. This varies by state/country of course, but in general I don't advise going into law because it isn't worth the costs to get in for most. (though just like art, music... there are some exceptions)
Bets that this won't happen in just 10 years?
DARPA Grand Challenge took 20 years, and it's still not on the interstates. Waymo is amazing, but it's still a work in progress.
I know it's coming, but solving problems that require 99.999% correctness is hard work. Mistakes multiply.
A toy can be ready tomorrow, but a precision legal tool needs to be better than humans. Not unlike driving 70 mph on the interstate highway with hands off the wheel.
