Good read. Completely off topic: He traveled by sleeper train and mentioned that he slept reasonably well and very well on the return trip. In the beginning of my career I made nearly the opposite trip to Brussels by sleeper to a completely useless lobbying/networking event with little tangible content. Often sleep in sleepers is not very good. But on the return trip I only wake up when the train had already stopped at my destination and had to get off very hastily. Not only CS was more fun without AI slop, but traveling, too ;)
