Almost certainly self driving vehicles of all kinds. Even in the absence of any major ML algorithm breakthrough, I believe there is enough work already accomplished where the industry can grind out a well functioning solution in 20 years. This kind of time frame is long enough where I think that level 5 fully self driven cars will be available from major brands at prices that will make it affordable even for middle class buyers.
