Launching a start-up means learning by experience

I spent almost 3 years looking for the perfect and most advanced technology in Computer Science, well in fact it was just a few hours a day. At the end, what I found is that technology per se is not the business, technology is just a tool, a tool to fill a need for something. I had the idea of knowing about high tech and management, meant business, but fortunately I realized that in fact 2 ecosystems come together to launch a business.

The last week I attended 2 really top science presentations, one of them talk about how difficult is to make a new professional profile based on Computer Science and Medicine. Nowadays neither of them want to pass from one side to another. The same happen to science and business, specially for business where enforcement governs.
One particular case is high-tech start-up, where all is new, entrepreneurs are trying to build a no precedent business so we don't need to learn by studying, but by experience it. Thus I understood what this quote means "To have a great idea have a lot of them".
And most important is to be willing to go through from one ecosystem to the other one..
