I think both of these are pretty high bars, especially since Lawyers bill by the hour.
Finding a good efficient lawyer is much more about the Lawyers personality, knowledge, and ability and much less about the technology. A good lawyer can solve things very quickly at little cost. A bad lawyer can take the same matter, spend a ton of money researching it, working it, discussing it, etc, and still come out with a poor result.
I'm interested to see what he's building, but I won't be surprised if it doesn't upend the legal world.
