It was not an autopilot that crashed the two jets! Even if it had been, that would not change the fact that autopilots are a solved problem for IFR. The operating conditions where they can be used are clear, regulations are in place, and the risks are known.
I'd actually compare the Boeing "assistance" to the Tesla "assistance" as sometimes the craft will decide to steer into solid objects based on misinterpreted sensors. But the comparison is a stretch.
