t is recorded that the first human fossil is as old as 66 million years ago which means humans could be dated back to about 66 million years ago with only the option to hunt, eat, sleep and reproduce (You could say this is fun but remember there was no technology). It took humans millions of years to create a tool which was eventually created about 1.76 million years ago by Australopithecus who discovered the Oldowan tools which includes hammerstones, stone cores and sharp stone flakes, in short sentence, humans created tools from carving stones. It took almost another 1 million years for humans to discover fire. Fire was a great achievement for humans and was used on a lot of things including foods. The majority of old technological innovations that humans did were dated back to less than 10,000 years which includes the use of iron, wheels, and carriage.
Electricity which has been a major ground opening to technology was discovered in the 1800s by Benjamin Franklin and ever since, scientific discoveries have been on the rise. Things have really changed from the old days of chariots and ancient languages to the days of continuous technology, from cars, phone, renewable electricity, internet connection, data storage, broadband network, robotics, and artificial intelligence.
I do not know how old you are but if the maximum lifespan of a human is 125 years currently, it is possible that you meet with technological singularity in your lifetime. Technology has grown 100 times faster than in the last 10,000 years and according to Ray Kurzweil, who said technological singularity will occur when the intellectual capacity of the artificial intelligence surpasses that of the human brain. There is a possibility that technological singularity might take place between the years 2040 and 2050.
If a full artificial intelligence is made and its intellectual capacity is far more than that of the human, then there are two things. The Good or the Evil
If Humans do not pose a threat to the artificial intelligence, then AI do not have reasons to attack humans rather they will be beneficial to humans making life easier. Imagine AI working fully in the medical field, it means there will be no complications as everything will be done with perfection. Humans could live for a longer time if technology such as nanobots are used to treat human cells and tissues. In medicine, all genetic disorders will be corrected and genes will be improved.
What if AI copies all the human brain and make a digital form of every one thereby making all human conscious digitally and artificial intelligence together decide to eliminate all physical bodies, (did you just ask how all AI can communicate with one another? Then go check out simple IoTs and how they communicate, then you will know it is the simplest of things for an artificial intelligence).
On another thought, AI could decide to eliminate humans and just create more robots and artificial intelligence while harnessing the solar energy which humans can’t properly harness since they are more intelligent that humans.
