But then hindsight is 20/20.
My most successful "this is doomed to fail" grouchiness was social media games (like Farmville).
But I just can't think of any examples in the dev tooling space.
You can rightly avoid new things 99% of the time, but if you miss the 1% of things that matter, you get left behind.
On the other hand if you adopt the latest thing 100% of the time and 99% of those things are a waste, you will probably be fine.
