There's always something 'wrong' about tech people wanting to meet face to face. What is the point of the telecommunication tech YOU created? Did you not do a good job?
There's a better approach than what the blog outlines - imagine that you have infinite wealth and begin to build what you personally want.
In most cases you will not be able to create the whole thing, but you can tackle a piece of the problem.
Example - you want a flying car. Imagine that you have 1 trillion dollars at your disposal. What would you do? Hire engineers. How would you hire them? What software is required. Look around, if it does not exist already, that's your first product. If it the hiring problem is already adequately solved, look for the next thing. How do those engineers communicate? etc.
These series of questions will lead to finding niches of opportunity, and it is always a software problem (organizing workflows).
