This is somebody who watches Star Trek and figures that if they can use dilithium crystals to control anti-matter plasma conduits, well gee how hard can it be? We should get right on that.
I'll cut him some slack because he wasn't actually alive in the 70's but seriously, cure cancer? Is he not aware of the billions of dollars of investment in that problem? Did he not even realize that the cell biology research that came out of figuring out AIDs wasn't even freakin' POSSIBLE in the 70's? You couldn't do analysis on DNA in the 70's because the machines that did that, would take until the present day to give you an answer. Think about that.
Famous quote from Marvin Minsky along the lines of you want to solve a problem that will take a million hours of compute time, you can either spend a ton of cash and buy a super computer, and start it on its way and wait 114 years, or you can invest the money you have in a savings account, wait 20 years and then buy a computer at Fry's that will solve it in an hour.
We couldn't even build the tools to build the tools yet in the 70's that we regularly use to put cool features into an iPhone today.
So basically I'm offended on behalf of every engineer who lived and worked in the 70's at his comments.
And then lets take the flipside, given that we do have all of these amazing tools at our disposal, do you think people are not trying to cure cancer, in all its forms? So Peter has some genius idea that the Memorial Sloan Kettering Cancer Center's staff of doctors isn't considering?
Technology did not "stall" in the 70's. It has been accelerating at an exponential rate for decades. I can't believe he really thinks that.
