One reason that we may abandon a technology is that the costs outweigh the benefits. Thus the fridge has been abandoned because the cost of maintaining it outweighs the benefit of keeping lunch cold. Other reasons might be that the technology is no longer supportable (for example, if you cannot access fuel, your car is not going anywhere) or another technology appears/reappears to replace it. In this post, I would like to propose a theory by which some, or potentially many, modern technologies could be abandoned. This is an important issue because of its implications for government policy, business investment and of course society as a whole.
