A technology that hasn't been invented yet that would be good is a smartwatch that can detect diseases. This could be really helpful to many people around the world. It can help prevent lots of sicknesses and diseases, for children, adults, animals and many more. It would be put to good use and i think lots of people would be really interested in it. I would take lots of time and effort to create this, but i believe it will be worth it. The inventer would for sure make a lot of money out of this product. This is also something that could be used forever and for a long period of time, so that would make it better because we wouldn't have to worry about it running out or that we will only be able to use it for a short period of time due to people no longer making it.
