Just curious, on what do you base this opinion? Do you work in cancer research, or another biomedical field? These tools will definitely advance our understanding, but my feeling (as someone who worked in genomics for several years, though not in cancer) is that if you think "we are really close" to curing cancer (pardon me if I misinterpreted your statement) with these technologies, you are buying into a lot of hype around them. It's natural that that hype exists, though, given how much VC money is being poured into this area right now.
