Wrt the Singapore summit, every participant got a huge personal return on investment. I can easily imagine a similar PR deal with Putin.

Engineering vs Math

I've been thinking about this.

It looks like risk profiles of the two human activities are quite different. There's very little redundancy in [complex] math proofs/procedures, while many engineering systems are explicitly designed to be redundant. Failures in math are unforgiving, while in engineering they are broadly expected and maintenance/recovery measures are often built in.
