Bootstrapping is the process of getting better at getting better. Things that bootstrap exhibit exponential improvement.
The advantages of building tools to think and build better tools is obvious. One drawback — bootstrapping has high up-front time costs. Rather than focusing on finding a, you're going one level deeper, one level deeper, one level deeper, to build the tool that builds the tool that builds the product.
This approach often works well in research lab environments, where the runway is longer and the goals are not commercial profit.
Dilemma: can this approach work in a commercial setting?
