Your brain peaked musically somewhere around age 16. Everything since then has been a dopamine echo. Between the ages of 12 and 22, the mesolimbic dopamine pathway, the same circuit that processes cocaine and sex, fires at levels in response to sound that it will never reach again for the rest of your life. A 2011 McGill study used PET scans and fMRI simultaneously and found that music triggers dopamine release in the striatum at peak emotional arousal. The caudate nucleus lights up during anticipation of the good part. The nucleus accumbens lights up when it hits. Your brain is treating a guitar riff with the same reward architecture it uses for food-seeking and pair bonding. During adolescence, that response is dramatically amplified. Pubertal hormones are flooding the system. The prefrontal cortex is still wiring itself. Memories formed during this window get encoded with a density of emotional tagging that nothing in your 30s or 40s can replicate. Researchers at the University of Leeds identified this as the “reminiscence bump”: the period when your sense of self is forming, and the music playing during that formation becomes structurally integrated into your identity. A 2025 longitudinal study from the University of Gothenburg analyzed 40,000 users’ streaming data across 15 years. Younger listeners explored broadly across genres. Older listeners collapsed into increasingly narrow loops, almost entirely anchored to music from their teens and early twenties. Your brain stopped losing interest in new music years ago. It’s running a cost-benefit analysis. Familiar songs deliver guaranteed dopamine with zero processing cost. New songs require pattern recognition, expectation-building, and repeated exposure before the reward circuit kicks in. Past 25, most people stop paying that tax. The one variable that predicts whether someone keeps exploring: the personality trait “openness to experience.” Score high, you keep seeking. Score average, you default to the familiar forever. The fix, if you want one: deliberate exposure. Three listens minimum before your auditory cortex builds enough predictive models to generate a reward response. One passive listen on a playlist will never get there. Your brain needs repetition to find the pattern, and it needs the pattern to release dopamine.

Unfortunately, as you get older, you gradually become less interested in new music and keep going back to the old favorite songs you once loved.

Charlie Munger: "One of my favorite tricks is the inversion process." "If somebody hired me to fix India, I would immediately say, 'What could I do if I really wanted to hurt India?' I'd figure out all the things that could most easily hurt India — and then I'd figure out how to avoid them." "It works better frequently to invert the problem."

Behold one of the mightiest tools in mathematics: the camel principle. I am dead serious. Deep down, this tiny rule is the cog in many methods. Ones that you use every day. Here is what it is, how it works, and why it is essential:

New work: Do transformers actually do Bayesian inference? We built “Bayesian wind tunnels” where the true posterior is known exactly. Result: transformers track Bayes with 10⁻³-bit precision.

I was sitting with an older animator watching Disney's first feature length cartoon, Snow White. We both were amazed at the film. I asked him "How much do you think it would cost to make this today?" I'll never forget his answer... "We can't, we don't know how to do it."

Before (left) and after (right) of the interior of Notre Dame. Modernists lost this battle, so instead of a glass spire and partially destroyed vaultings everything was reconstructed as it was. Architects, for example, made sure that the former Medieval assymetrics in the central vaulting with the oculus (which was there due to lack of precision tools) became recosntructed exactly as it was before. The walls and windows have been cleaned of centuries of grime and a new adjustable lighting system has been installed rendering the interior of the church ever brighter. The Holy Mass of rededication will be celebrated on December 8.
