It's naive to think that a company would develop an AI capable of beating a lawyer in court and then sell it cheaply to poor people to beat traffic tickets. If anyone ever manages to develop an AI that is actually capable of replacing a lawyer, it will be priced way, way out of reach of those people. It will be sold to giant corporations so that they can spend $500k on licence fees rather than $1 million on legal fees. (And unless those corporations can get indemnities from the software vendor backed by personal guarantees they'd still be getting a raw deal.)

These people are being sold snake oil. Cheap snake oil, maybe, but snake oil nonetheless.
