Great article! I don't buy the 'singularity' idea either.<p>It makes for fantastic science fiction but in the real world all resources are finite and every technology we've come up with so far has had to deal with the harsh realities of the thermodynamic laws and regular materials science. There is plenty of room at the bottom, indeed, but the bottom is not 'bottomless', and the engineering problems are formidable.<p>Sure, there is progress, and plenty of it. But to think that that progress is 'easy' or 'accelerating' belies the enormous amount of hard work that goes in to achieving it.<p>And with every step every next one becomes harder, the laws of diminishing returns.<p>I think that our illusion of ever accelerating progress has more to do with the fact that ever more people are 'knowledge workers' and 'scientists' than anything else, the greater a fraction of our society that advances our knowledge the faster we will move forward in this respect.<p>The 'uploaders' are essentially practicing wishful thinking about that great question plenty of people have had to deal with in the past: How to avoid dying.<p>Unfortunately I don't think any of the people alive today is going to be able to accomplish that feat, statistics is overwhelmingly against it, everybody that ever lived in the past has died before the ripe old age of 150 of one cause or another. And so will everybody living today.<p>If you want to be immortal your best bet is probably to write a book, compose a piece of music or make a timeless movie.<p>I'm not sure if blogging counts :)<p>And as for the singularity, there are several other scenarios, some plausible, some implausible:<p>- a plateau of knowledge after which any future gains in knowledge will come ever slower, in a world like that new scientific findings would be real headline news instead of the science section on page 24<p>- a 'wall', beyond which we will not be able to go without knowledge 'behind' the wall (physics may be up against that, or maybe not but if there is something beyond quantum may never become a settled question)
