> Before CRISPR came along, I remember talking to someone working in archaebacteria who went on and on about these arrays of sequences in archea that seemed really fascinating to him, but I never quite got the implication of what this would eventually develop into before it actually did become CRISPR (by other people working in the field). >I remember ~20 years ago hearing about nanopore DNA sequencing, and wondering if it would ever work (it does!). These two things are very different to my eyes. Nanopore sequencing seems obvious to me as an electrical engineer. The basic problem was noise and control--which you could probably solve with computes and Moore's law. You can fund it, but it feels like something you could leave to industry as it seems like it's engineering more than science. CRISPR is non-obvious. It's more in the realm of Taq polymerase--it's interesting but, so what? Well, Taq polymerase would become the keystone to PCR about 15 years later. I'm much more interested in figuring out how to fund the things that later become building blocks rather than pouring money on something that industry is likely to do anyway.

Industry will only ever fund things that are easy to monetize in the very short term. Translational research can be just as important as basic research, so both should be funded when they are plausibly in the public interest, regardless of any private returns.

ASML worked on something for two decades, and now, against all odds, EUV works :) But, of course, it is notable because it is far from the normal case. And it was, more or less, an engineering problem, which required some support from scientists.

Both of those issues: 1) slowing down the DNA, and 2) finding enough change in current to be able to distinguish bases, did not seem that they could work out. You really have to solve the first before you know if the second is solvable, but getting tiny molecules to behave as they flit through protein pores is not a trivial task, particularly around ~2000. The signal processing is still quite significant, and I hear that if you don't have a compute box that's set up correctly, you can't get data to and from the GPU quickly enough for base calling (no personal experience, just heard friends griping about early experiences). So even with todays compite tech, the signal processing is pretty heavy duty, 2000 era hardware and algorithms would have far far less accuracy. Which is all to say that yes, now it works, and my uncertainty was perhaps unwarranted. I'm super impressed that it works, and I've learned a ton of humility about guessing what other people can figure out how to do. David Deamer is a visionary, and all the people that worked so hard on it afterwards deserve major kudos.
