When I researched COVID-19, I touched upon a lot of molec bio stuff that I had no idea about before.This is something that I love reading and thinking about but never get to talk about. Hence I will likely forever be an exceptional individual on this topic.
It's obvious that one thread is not enough to efficiently discuss everything OP brings up. But it's a well structured effort. I'll try to say something "productive." And I will spoiler my main points.
Nanotech/nanomachines have MASSIVE implications for medicine, e.g. in age-related disease. I think some people have an idea that nanotech/nanomachines in humans will be actual tiny robots swimming around in your blood breaking down amaloid plaque/LDL/whatever in best case or malfunctioning and breaking down your muscle/neurons/whatever in worst case. In reality, nanotech (as it's currently developing) will be highly specific molecules that can only do one function. Think of proteins (including enzymes). DNA can be modified to produce proteins that prevent/treat certain diseases (this links back to "synthetic biology"/GMO, as stated by OP) but that's not coming anytime soon. And notice I am NOT mentioning synthetic cells. That's a whole other topic.Exoskeletons have massive implications to industry and military. I could go on about this in the context of OP but "mech suits" aren't my only interest. Hapic suits are another intruige. They are wearable tech that is being used a lot for VR gaming now. However, a few years ago, these were being developed to help certain sorts of deaf people perceive sound. The intent makes sense; sound is vibration and you are deferring/redirecing that vibration to different parts of the body to help people "hear." This sort of suit was also being tested to help train pilots in understanding the mechanical status of their aircraft without visual stimuli. In this context, exoskeletons can be used to more thoroughly and non-invasively integrate tech into our body schema. Anyone who has kept up on this, please let me know.
The above two fields, I strongly endorse and think should be researched and developed as quick as possible. But of course that is not all of the tech/engineering OP mentioned. I have nothing else to say about the other topics rn. But I have two smaller points to make:
People have already brought up immortality in this thread. I think human culture around death, in general, is terrible and results in a lot of extraneous suffering. I am occupationally obliged to deal with a lot of death. Thus I hope people can separate their emotions about death from the topic of "transhuman" tech. It will be a long time before we "end" death, if ever. I don't think this should be the focus of current discussion.
A lot of qualms with "transhuman" tech, I think, can be alleviated by education. Hence I think basic medicine and neuroscience should be introduced in high school/secondary school. There are a lot of technologies that can help us (our species and even our ecosystem(s)) develop and survive without enslaving us to Skynet.
TL;DR some of this stuff just needs to be in healthcare already.

I can tell you why people age, and why we die. To put it bluntly, our environment is caustic to us. Living, itself, is what kills us. We're exposed to entropy all the time. Oxygen radicals damage DNA, and so do cosmic rays. Telomeres and the Hayflick Limit are there for a reason. Past a certain number of cell divisions, there's no way to know what the quality of the DNA is, because every step of the copying process is lossy. Some people speak of lengthening telomeres as if it's a cure for death, but it isn't. A cell with lengthened telomeres might divide more, sure. But it may also become the nexus of a tumor. The cure for death is the repair of all the DNA in all of your somatic cells, back to a healthy baseline, along with the clearance of all "junk"; senescent cells, amyloid plaques, et cetera.
All of the cells in a human or animal body are essentially tiny nanomachines. DNA forms the bases of one's genes, and genes are essentially blueprints for proteins. A cancer cell is just a mutated cell that replicates out of control and refuses to die when ordered to.
I can see ways to rejuvenate cells. Perhaps the delivery of refreshed genetic material by means of viral vectors. However, the trick is getting it to integrate into the genome correctly, without introducing new errors. Easier said than done. There are many different cell lines in the body, each with their own unique needs. Personally, I don't think achieving biological immortality in humans is an insurmountable problem. It is, however, an extremely difficult problem. If you could truly solve aging, you could also convert tumor cells back into normal cells, and so on.
