I have a lot of "mad science" projects, but only to help me make my work easier. I would never try to turn any of my work into products for sale. Selling tech to lawyers and law firms is a good way to make yourself completely miserable. (They are nearly always nightmare customers.)

Lawyers and law firms currently have no serious imperative to work efficiently. Until companies let go of their reliance on big law firms, this will continue. I hear a lot of talk about people wanting lawyers to change, but then if you talk to any funded started, they nearly always either waste a ton of money on expensive law firms, or they avoid lawyers altogether. It's a complicated problem that perhaps only time can change.
