Haven't we had this before? Anyway, this is all explained in Tainter's book Collapse of Complex Civilisations. I couldn't be bothered to go over it again, but it's been covered already.
The rate of technological innovation is declining, and it is significant. More importantly, the "bang per buck" is declining, which means we would have to put more money in to get the same rate of innovation. In fact, this may be one reason why the rate of innovation is declining.
Don't get me wrong, I love technology. But it really is running out. The Red Queen effect is there, you only have to look at antibiotics. The early innovations were mainly about macro scale thigs which gave a great bang for buck : steam engines moving bulk cargo. Do you know what held back the Roman Empire? Mass transit. Land transport was expensive. It cost more to transport grain over land from Southern Italy than it did to get it by boat from Egypt. The Romans would have loved to have steam trains.
Now, the clever stuff is scanning electronic microscopes which can position one atom. Wow! But it costs millions, and moving one atom at a time is not just slow, if you consider a gram of hydrogen contains 6x10^23 atoms.
So unfortunately, we are rapidly reaching the limits of our big earth moving technology. Moving single atoms will never be worth it. If we could truly genetically engineer stuff, things might be different, but we have barely even begun to understand how living things work, let alone build one. Directed evolution is a possibility.
It is true that discoveries have been made as much by chance, than by directed efforts. Unfortunately, this and the other myths of wondrous technological progress are exposed as false.
I see the usual suspects tip up to bang their drum of technological progress. If you love something, it can be hard to let it go, but sorry guys, not all science fiction comes true. The future will be less Star Trek, and more Soylent Green. Who knows, we may get another breakthrough, but its going to take a lot more than "one click shopping".
It's all downhill from here
