Public transport doesn't compare to robotaxis. If robotaxis become a reality I expect a significant drop in car ownership and public transport use. The price will be competitive with the price of public transport, at least for single fare prices.
I can catch a bus every five minutes a one minute walk from my house in Utrecht. Those buses go anywhere. In Oslo I could ride the T-bane to the forest or to downtown. In Tokyo it was obvious public transit is the only way to go. All the places I lived outside the USA I would never take a taxi much less a robot one in lieu of Public transit.
