Polypeptides, amino acids, proteins and molecules, building blocks. Nanotech, the new construction technology. Think of the breakthroughs. The lame will walk, the blind will see. Pocket sized supercomputers, truly lifelike robots, real six million dollar men.
And think of the drugs. I'm not talking gene therapy, but rather the recreational type. Take an actual soma holiday, two weeks in the Caymans experienced in an hour real time. Dream the dreams of Picasso. Think the thoughts of Einstein. Re-experience the womb as an adult.
And it will happen too. Because there will be a market and profit, your justifiable horror aside.
