Fair question MFM, but I can distinctly remember when the popular thought was twiggy forrest was a dreamer, branson a washed up hare brain with no chance of real success, and Barry Marshall was considered by the medical establishment as being full of it, until he proved them wrong and got a nobel for his discovery. Which led to the treatment now enabling me to enjoy a beer without it sitting painfully in my chest cavity on a frothy layer of gastric acid. Disruptive people - you've got to love them!
