  • It’s because dropping out is 100% not in Trump’s character. He’s in the race for himself, everyone - even his supporters - knows that, and asking him to drop out is like asking a zebra to try all-black.

    Biden, OTOH, is a public servant and presents himself as trying to do the best things possible for the country. He ran in 2020 to ‘save us from Trump,’ and he’s running again with that premise. You can disagree with Biden on what is best for the country, and maybe convince him that someone else might be better able to beat Trump in 2024. I’m not really all that engaged, so I have no idea who the next-best Democrat would be, but Biden stepping aside is at least within the realm of conceivable possibilities.






  • Even if you ignore all the neuromodulatory chemistry, much of the interesting processing happens at sub-threshold depolarizations, depending on millisecond-scale coincidence detection from synapses distributed through an enormous, and slow-conducting dendritic network. The simple electrical signal transmission model, where an input neuron causes reliable spiking in an output neuron, comes from skeletal muscle, which served as the model for synaptic transmission for decades, just because it was a lot easier to study than actual inter-neural synapses.

    But even that doesn’t matter if we can’t map the inter-neuronal connections, and so far that’s only been done for the 300 neurons of the c elegans ganglia (i.e., not even a ‘real’ brain), after a decade of work. Nowhere close to mapping the neuroscientists’ favorite model, aplysia, which only has 20,000 neurons. Maybe statistics will wash out some of those details by the time you get to humans 10^11 neuron systems, but considering how badly current network models are for predicting even simple behaviors, I’m going to say more details matter than we will discover any time soon.














  • I feel like the 2022 turnout is more down to the unique conditions and issues, across the age spectrum - especially Dobbs and election lies - than to anything specific to 20-year-olds. 28% turnout still means that the vast majority of GenZ can’t be bothered.

    I mean, the handful of GenZ that have reached adulthood do seem marginally more active than other post-war cohorts, but they aren’t overthrowing historic voting trends. Pinning hopes for future political outcomes on them is as foolish as pinning the future of US democracy to black voters, or hispanic voters or any other minority/niche population, but media love doing just that. Just try googling “black women save democracy.”
