I don’t know if this story is true, but someone (person, blog, … I don’t remember who) had told me that when the first car was build the other people said that it is useless since there are bicycles. They would never need a car since the most places that they had to transport themselves to, were near enough to buy such an expensive machine.
The same with personal computers, cable phones, mobile phones, internet, open source, electronic money, e-commerce, wikipedia, blogs, online social networks, online activism etc.
I remember to tell when Mercedes had released the first self-parking car, that this is too expensive for such a simple task. But now we have self-driving cars from Google. This is the way research works.
So when you see a product like a washing machine that connects itself on the Internet, don’t tell that this is useless. Just picture a better future. The future of the Internet of Things. Yes it is here and I know that because I am working on that!
