This sounds like Grace Hoppers rant about hanging 1K feet of optical cable (speed of light @ 1 microsecond) around the necks of programmers that wasted microseconds of compute time.
Computing requires exponential gains so that we can compute additional layers of abstraction. It makes it possible to program what we do. The reason usability has gotten better is because we don't need to write hand-tuned machine code just to get UI widgets working.
And do not tell me that the IT department are that much better than users, usability IS security. Make super secure passwords, users will write them down. Make it hard to install apps, and they will disable security. As Kevin Mitnick has shown time and again, people are the weakest link, not the technology.
Don't worry, we will get encryption and other privacy enhancing products into the hands of end-users soon. Just look at Chromebooks and the iPhone, both have lock-down capabilities that far surpass the average corporate desktop.
