Thanks for the article link. I don’t agree with the concept that we should have some goal to “never add any risk to bitcoin” because there’s no such thing. 

Not having critical primitives for scaling sovereignty is absolutely a risk. Not enabling ways to create more expressive layers is a risk. Adding additional locking types and designs is a risk. Adding introspection is a risk. Everything has risk. 

There are no solutions, there are only trade offs. The day we forget that, we lose our ability to make an honest assessment of anything. Bitcoin is not perfect, it’s simply the best we have.
