"Easily approachable" doesn't mean I can just go ahead do it. It means I can see how one would start working on it, and in fact many people are.
In fact, I am currently working in a nanotech lab, so I am hopefully helping a bit ;)
None of the problems you linked to are things that need to take a hundred years to solve. It's probably more accurate to measure development barriers in R&D costs than years. At the very least, we could just reverse engineer biology.
Doing experiments on animals (and especially humans or other vertebrates) is the exact opposite of something you can just go ahead and do. The best way to see that is to give it a go yourself.

Many people in the past with a CS/physics mindset have made similar claims. If you try to work with living systems, I'm sure you'll see why these problems aren't just a matter of spending R&D dollars.
