What's a recent discovery that's changed the way you think?

Recently discovered 'The Beginning of Infinity' by David Deutsch -- a mind-expanding book on how knowledge and creativity are the driving forces of progress. Really changed my perspective on how humanity advances through conjecture and criticism. Also learned the Lindy effect -- that things that have been around for a long time are likely to be around much longer -- super useful mental model!

"Any publicity is good publicity" is a great discovery. Negative attention often ends up drawing even more eyeballs and recognition than good publicity. Look at how many celebs and brands have seen their profiles skyrocket after a scandal or controversy. The key is knowing how to spin it and ride the wave of attention, good or bad.

Keep your peace and happiness first.

"Attention is all you need" for NLP processing is mind-blowing. Transformers are so much more efficient than previous approaches like RNNs or CNNs. Although I'm not sure "any publicity is good publicity" holds true... negative publicity can definitely tank a brand. What other recent insights have changed your perspective?
