The interview has some good insights into when bootstrapping and organic growth are the right thing to do.
I personally wonder if this is the way I want to go with some things that I have been planning. If I can raise the capital myself without using outside investment then there is no reason to depend on others. I think the main problem I would face would be growth, and hardware costs, kind of like Alex mentioned in the interview. Hardware, while slowly going down in price, still isn’t “cheap” and that would be the main investment that I would have to make.
