a couple years later, i still like my framing of AI as "easy access to statistical likely stuff" -- and the question of what is likely and not, and how far you can push it toward what people want with targeted data collection, is still very unintuitive.

in 2014, I bought 3 nest thermostats for my house, which cost like $600… 10 years later, google apparently can’t afford to keep the api running, but had offered me an option to pay $250 per thermostat that will do exactly the same thing as my old one #internetofshit

you can't make a technical contribution in HCI by just connecting an LLM to something. we need to know how it works, beyond a user study with a few people. what are the ways that it fails? how fundamental are these problems, what does it reveal about the potential of this kind of use, etc.

i know there are too many reviews, but i'm really uncomfortable with how many folks seem to be looking for reasons to desk reject papers based on minor or possible "rule" violations. so many examples that i personally know of, suggesting a wild trend.

they say trump isn't an autocrat, but what's more autocrat than using the powers of government to show videos about how your opponents are bad. i'm glad folks are resisting this, but also i feel like people aren't dumb and seeing this nonsense may help illustrate the problem.

i think in 20 years, we might see the biggest existential risk having been the bad metaphors and examples given by "AI risk experts" -- at one point, this particular person anthropomorphizes natural selection into a metaphor for AI risk, completely mischaracterizing what natural selection is…
