I have seen some speical type of taxis running on the streets without drivers a few months ago. We know that many people support families as a taxi driver. If AI replaces taxi drives, the boss who is in chage of the taxi business will earn a lot of money without paying money for drivers. The taxies which are controlled by AI would provide better serive than common taxies. The AI can help guests choose the best roads to get destination. They are even more safe than common taxies. They can avoid accident by AI. All the advantages of AI taxies sound great. On the other hand, the drivers who have been get fired lost the ability of making money for their families. If nobody cares about them, what will they do for a living in the future?
