As my kids would say, "Ooooohhhkaaaaaaayyy ...."
But seriously, folks ...
Articles like these call to mind similar articles written decades ago, where various scientists explained why no one would ever run a mile in less than 4 minutes. (Ooops.)
Meaning, someone will break through this supposed barrier someday. And others will follow.

Think of Brad Penny in the All Star game. Here's a guy who's usually content to throw his fastball in the low 90's, but since he's on the big stage with only two innings to throw, he lets it all hang out and pumps 98-100 up there for two innings. He blows 'em away in the first inning, and seemed prepared to K all six batters he would face. It was an amazing thing ... until Vladimir Guerrero deposited an eye-high heater into the right field seats. Then we remembered that the Brad Penny who throws in the low 90's also throws other pitches and tries to use his head, and that guy was 10-2 heading into the all star break.
