Enrollments are somewhat up compared to the past few years, but still not particularly high, especially relative to the growth of the tech industry over the past decade. So I wouldn't worry about enrollment increases unless they get much larger.

Here's a graph, showing how much below the early-2000s enrollment peak we still are, even in raw numbers not adjusted for percentage of the population, or percentage of the degree-holding population: http://www.cra.org/govaffairs/blog/wp-content/uploads/2011/0... I think some of the perception is due to how changes are reported as percent-increases and percent-decreases: to reverse the 50% decline in enrollments that took place between 2004 and 2009, we'd need an 100% increase in enrollments currently, which we aren't anywhere near.

Plus, if you're good, it seems to be near universal consensus around here that it's very hard to hire good computer scientists, whether you're hiring for a startup or a larger company, so the supply/demand still seems to be very much in the supply's favor.
