Oh come on, this applies for ANY tool in ANY domain. This is non-information.
Take two programmers who are novices. Throw them into any two languages. If we use an automated DAL and a mentor-apprentice training paradigm in both languages, I can have the ASP.NET guy up and running and more productive faster than the other guy. <disclaim>for writing average run-of-the-mill web apps</disclaim>
That is my stupid way of saying, who gives a crap how long stupid ASP.NET guy takes to get productive? In the long run, inevitably, someone else will be better.
I liked it better with the forumlas. (grin) Seriously -- that's a good point. But I don't think it is language-dependent. Might be. I don't know. From what I've seen languages and platforms are just new and interesting ways for programmers to shoot themselves in the foot. Good programming remains the same now as it was decades ago. That is, unless somebody has started using the force and I don't know about it.
