This is unfortunately very true.<p>We don't have a stagnation of tech progress, we keep going forward- but the grow rate seems to be decreasing.<p>Some people apparently think existing innovation (ex: mindstab comment) suffice to disprove this.<p>It's not.<p>Just look at the 40 or 60 to see some real innovation - like antibiotics, nuclear bombs- i.e. paradigm changing innovation in various domains.<p>What did we got lately? Computers, internet, cellphone, social networking - ok, but it's a bit short, and it's mostly in one domain only.<p>IMHO, for any self consistent conservative, it's far more worrisome than theoretical weather change, especially because we got used to this fast pace of innovation and growth, and there have built the core of our societies on such assumptions (interest rate for money, population grow for social security, etc) - like, we are expecting technology will improve so that we get new ways problematic (orbital mirrors, tweaking the albedo, ...) to fight climate change if it is indeed man made and<p>The idea of a deceleration of progress has some merit - to me it's like multiple warnings indicators lighting up, even if I don't know any theory to explain it, except a reduction of the "will to live" in western societies (Nietzsche style)
