Some thoughts on the SENS4 conference at Transhuman Goodness: "The conference included around 90 talks, most of them by academic biomedical researchers, many of whom from 'serious' universities such as UCL, Cambridge University, etc. A typical topic would be 'we have this hypothesis about how this part of the ageing process works, and we tested it in this trial/we built this device'. ... Now, as far as conquering death for those people who are currently within a few decades of dying goes, we are going to have to do an awful lot more, and pull out a lot more stops than I saw evidence of at SENS; if there's one overriding impression I really want to avoid, it is the impression that now that SENS exists, the ageing problem is handled, for that would be a fatal mistake to make. The problem of ageing is a very hard one, primarily because the human body is very, very complicated and very, very messy. The average biomedical talk given at SENS, which represented the work of a few researchers for a total time of perhaps a few months to a year, would typically make some small increment of progress on some small subsystem of the human body, and in some cases that progress was the refutation of some previous promising piece of work. ... Coming back to the subject of the conference itself, I was pleased overall: it was well-organized, professional and contained a lot of good science. ... My thanks go out to and all those who worked hard to make the conference a success; we should all be grateful to those who work towards the betterment of humankind by trying to defeat ageing, for they are the true heroes of our time."
