💎 On the danger of only evaluating projects on what is easy to quantify

A question was given to a bunch of engineers about fifteen years ago: How do we make the journey to Paris better? They came up with a very good engineering solution, which was to spend £6 billion building completely new tracks from London to the coast and knocking about forty minutes off the 3.5 hour journey time. It strikes me as a slightly unimaginative way of improving a train journey to merely make it shorter. Now, what is the hedonistic opportunity cost of spending £6 billion pounds on railway tracks? Here’s a thought; what you could do is employ the world’s top male and female supermodels, pay them to walk the length of the train handing out free Château Pétrus for the entire duration of the journey. … At which point you’ll still have about £5 billion left in change, and people will ask for the trains to be slowed down.
