> What's wrong with fad and hype driven development?

The "flavor of the month" band wasn't as good as The Rolling Stones. That's not the end of the world if all you did was buy their CD, and then never listen to it again after the month was up. If you completely rebuilt your stereo to try to make that CD sound better, though, that gets more expensive. (Especially if you rebuild it again next month for a different band.)

Development is more like rebuilding the stereo than buying the CD. It's expensive. It takes time and money that could be spent on other things.

Worse, in replacing dependencies, you may replace a dependency on something that works with a dependency that doesn't work nearly as well. You may replace your Corvette with a Corvair. (And spend time and money to do it.)

If you have battle-proven tech, there is a place for eventually replacing it. Eventually, though. Not very quickly. And when you do replace it, don't replace it with the fad of the month (or even the fad of the year).
