There is no getting around the fact that projects that used to take man-years are possible in an afternoon now.
And this is the worst this technology is ever going to be :)
Don't take my word for it, go try building something that you always wanted to build but did not have time for. If you do not have something like that at the back of your head, I doubt you have to be concerned about this topic.
What did you build that would have gotten man years before?
