Well, every new technology inventions usually comes with a high price, and only affordable by a few rich individuals. However, as time goes by, the cost for acquiring them become lesser. Just think about mobile phone for example, when it first came out, the price for a GSM phone was so high for the ordinary people. Gradually, as innovation takes over, mobile phone became cheaper for everyone to get. I believe the power of innovation will make AI and robots cheaper for everyone in the future.
