Information technology and artificial intelligence are advancing day by day. Scientists and technologists are working to improve them by leaps and bounds to make it easier for mankind to do work of all kinds, focusing on minimizing human time and effort. Various technology-rich countries' technology associations are working and researching for this purpose continuously. Japan is at the top of the list of highly technology-rich countries and has already produced housekeeping and guard robots. Developers are also working on robots that can be used as waiters or workers in hotels and shopping malls, respectively. Just imagine a world where nobody has to be a servant of anyone just for the sake of making a living. Imagine that, when nobody has to get cursed by anyone just because being a servant he/she can be treated like an animal. The world would be better place if instead of humans, we make robots our servants and our workers. In my view, by 2030, Japan or another country will take a step to launch robots that will work in malls as workers and hotels as waiters. It will be adopted by other countries soon as well, as it saves time and effort that humans once had to expand. Side effects:
1. There will be fewer jobs for uneducated or illiterate people, but that does not mean they will be starving. There will be other options, of course.
2. If a robot's system crashes, it will take time to repair or money to replace; thus it could cause a loss to the organization that is running the hotel or mall. Losses can be prevented by putting sensors and exception handlers in robots.
3. Only big hotels and malls will be able to afford robots; for smaller budgets, sorry, there is no solution but to wait.
