I would assume the first way to make use of genetic engineering would be, like always with new technology, applied for military purposes first and foremost.
Continuing this line of thought, if mass cloning became a thing and if genetic modifications could be done to these clones, it would likely lead to all kinds of new biological weapons. The clones would not even need to be in any state close to being recognized or acknowledged as human beings, for them to fulfill their purpose.
I could think of dozens of ways to put this into practice.
The last I heard about human cloning successes were when they cloned 30 embryos in China if I remember right.
Going down a different line of thought, living organisms and machines aren't all that different from each other in the way they work. You can make a machine emulate emotions or even experience dreams.
I would say chances are actually pretty high that humans are simply neurocybernetical machines.
Of course I'm not a neuro-scientist, but robots are big in the coming, not just for Google.
The 4th industrial Revolution has already begun.
Smart machines, just like genetic engineering seem to be current candidates with high potential for sudden technological surges. My second point being, I think that we might actually get closer to an understanding of how the human brain works through these advancements. And once we have this kind of knowledge, creating more human-like machines will in turn be possible as well. But the resources on the planet are finite and everything has it's limits.
If you can make a machine work like a human and a human like a machine, that only leaves the question which of the 2 available options costs less for each individual application. I could therefore imagine genetically modified organisms (not necessarily humans) partly replacing machines, perhaps not in areas that confront you in your daily lives often, but for example in aeronautics it would be a tremendous improvement to see a machine fly more similar to a bird or bee, just like it would be an improvement to see a mindless organism fly that way on the pilot's command.
A funny topic.
People that complain about such forum discussions not being scientifical enough because the discussions lack an empirical foundation kind of miss the point that this is a forum and not some science blog working with the goal in mind to bring humanity a step further. I don't see the harm in talking about things like these.
