This cracks me up. Modern web browsers really started to evolve in the 90's when security problems really ramped up. You used to just download excecutables and run them on your computer because the functionality wasn't there otherwise. Flash and Java applets were the initial answer to that before Javascript and HTML evolved. We've come almost full circle to browsers basically being little VM's that can do anything again, the main reason they were developed in the first place. Most people's entire computer experience is now in the browser and here come executables again which will require another internal layer to mitigate problems.
