When I see an independent study done by a group led by someone with at least a Master's degree in electronics or electrical engineering (preferably a doctorate) that shows a flaw in the 2.4 technology, I'll believe it. Some guy Googling a few pieces of information and drawing big conclusions based on logical fallacies (the article) isn't worth the time it took to read it. Read some real research or don't read anything! Sure, our radios are not 100% reliable. They never have been. But the widespread use of 2.4 has shown that it does work and does have some advantages that 72mhz cannot provide.
You can read Warren Plohr's credentials here:

The statement that should stand out to us is: Following World War II, Warren enrolled at the Carnegie Institute of Technology to complete his degree in aeronautical engineering.
He also taught himself radio electronics from the Radio Amateur’s Handbook.
He was also very concerned with Lithium technology being applied in our hobby when that issue was being discussed by the ETC.
He has been retired from NASA government service for over 30 years and may be just a bit behind the technology curve.
As for the "next" radio systems I have a couple of friends now flying on 430 MHz spread spectrum. Something readily available in the ham circles for experimental uses.
For every new techology there will be some expert to worry us about it. See the lead in to my November column in Model Aviation Magazine regarding an expert's comments on firearm development.
