You guys remember when Color raised $50m with no product and the valley went ape and started screaming bubble?
Talk about quaint compared to today.
ML has a very serious risk of spending hundreds of millions of dollars over a decade with no customer input building something that will land like Google Glass or a Segway. Then what? Someone like Google has other products and can retreat and regroup, but ML will lose whatever credibility they had and not be likely to recover. It could be very ugly.
