Eye opening (well I'm unsure if it is - the failure of acceleration pointed out has been apparent for a while) piece on a fundamental sea change in computing technology forced by the breakdown of the previously available "free lunch" of exponential hardware improvement.
Improvements in dealing with concurrency (from functional programming comes tons of way to do concurrency without thinking explicitly about threads) is definitely something to watch.
The benefits by the way are already appreciable as concurrency is already a design problem to be reckoned with in distributed computing - and with everything moving to the web who is not doing distrbuted computing projects?
For the ultimate in concurrency we need to go to quantum computing of course.
