expanding lifespan (in the way you are referring to) is not a requirement for progress. things like curing climate change and AIDS and war are though. and on all those fronts, we are making progress. AIDS might be eradicated within a generation thanks to things like Truvada, climate change could be solved if we got off fossil fuels and gave nuclear a chance, and war could be solved if democracies functioned well (instead of being corrupted by big money).
on all fronts there will be progress. and you can't deny it. technology and science are winning on all fronts and there is no competition aside from ingrained political interests. and they don't last long.
whether or not we have detailed knowledge of every single little thing at the current point in history is not important. what is important is that we have solutions to the problems facing humanity, and we do, plus we have plenty of more innovations that will improve things for at least a few generations
