MY SCIENCE INVENTION OF THE FUTURE

My experience today with my little baby girl brought about this topic. When I woke up this morning I was very optimistic and predicted that everything is going to go well today. Little did I know what today has in stock for me. My baby was feeling fine until after noon that she started frequent watery stool and temperature. She had exhausted all the diapers I packed for her from home and didn't even prepare money to buy extra. How I wish there is an invention that would be able to tell me my events for the day so I can be absolutely prepared for whatever is coming my way that day. I think it's going to be a very important invention because so many accidents, mishaps, embarrassment could be avoided and solved even before it happens. However, I don't think the invention will allow us know the true intentions of some people because they would have known ahead your reactions to some future events.
Nevertheless, I would still appreciate the invention because it's advantages would be more than the disadvantages. What do think?
