You sadly will find yourself in way too many discussions with bozos. The people who tell you that something can’t be done (not because they actually know but because they always say that); the ones who will tell you that it’s too hard (not that they ever tried, it’s just their default position); the ones who argue that you can’t win against the competition (not that they even understand your market all that well).
History is full of bozos:
Thomas Watson, Chairman of IBM said in 1943: I think there is a world market for maybe five computers.
Western Union wrote in an internal memo in 1876: This telephone has too many shortcomings to be seriously considered as a means of communication. The device is inherently of no value to us.
Ken Olsen, Founder, Digital Equipment Corp said in 1977: There is no reason why anyone would want a computer in their home.
You need to learn how to spot bozos and make a huge beeline for them. Tune into your bozo-meter and ignore their ‘advice’. Nod kindly when they lather their expertise on you, instantly forget what they said and keep pushing on your vision, strategy and product.
