Just think, if we just knew the benefits of personal and the Internet in advance, they could be reproduced in the 1950s. Primitive, like a now programable calculator, but working. The problem was only in the lack of understanding how cool it is, and the horse (with then-technology) price is beaten down once in 10 by some decisions, if it is purposefully to fight for them, rather than to make monsters for the calculation of space programs.
On the other hand, we might not have died at the age of 70. To make not even a clone, but just an immune-compatible fetus, you can now. It is possible to connect the spinal cord with an ENT transplant. The moral problems? The fetus does not understand that he is carried out to remove the brain, and then anesthesia and op, he is no longer there, and his body carries another head with another person; at what point and how does he suffer at the same time, if not to invent athral abominations? It’s primitive, but it’s better to live than to die with a perfectionist dream that one day you’ll be born.
The only problem is the lack of understanding how cool it is. After all, humanity is not yet familiar with relocating into a new body. As in the 1950s, it was not yet familiar with the Internet and the personal computerized workplace of each engineer.
Sometimes it is important to just want to. "And what, could it be?"
