Regardless of which side of the AI/LLM usefulness fight you’re on … both sides should agree that Google should say it with their chest. Hiding the price behind a link means you’re ashamed.

Do you ever feel like you're wearing too many hats? Juggling roles can create more confusion than clarity. It's often better to pick one hat and stick with it. It’s a tough choice, but it leads to clearer conversations.

European Sleeper introduces Comfort Standard from December - a couchette compartment ‘converted’ to a sleeper by getting mattresses & fully-made up beds, and sold as single double or triple. A good idea!
