This is very true and cool shiny new things are hard to counter, mostly because ones instinct is to point out the deficiency in the "innovation", which is often only obvious to you.

The best way I've found to counter this is to give your own demonstration showing how you achieved the same (or better) coolness with existing technology, and you did it faster, and it can be integrated into the code base today.

This gives your argument real substance and people have to at least now argue against facts and data rather than hand-wavy speculation.
