Do you buy that? I don't, for reasons I outline in a comment on his post. If you are jazzed about the technology (or aardvark farming, or whatever the topic is), nothing will stop you from learning more about it, on your own time and in your own way if need be. The information's out there on the Web to learn about pretty much anything, for free in most cases, so why not dive in? But, if you're not interested, your employer can shove all kinds of training down your throat and you still won't swallow. The excuse may be that you don't have time, but the reality is that you don't have the interest.
I would argue, hard, that these days, if you have the will, you'll find the way (including time) to learn. If you don't, any excuse will do, and time is a good one since everyone is so starved for it these days. Funny thing is that time spent learning usually ends up providing you with ways to make each of those precious minutes count a bit more. As Alanis Morissette would say, isn't it ironic?
