Intro. I’m a multifaceted weirdo, so in three parts:
① Homeschooled child prodigy, early/pre-web Internet’er, contributed to software used by ~2/3 of the world. Worked at multiple labs, including Bell/AT&T. Many successful startups.
Currently building tools to move forward science and computation.

The powerful portrait of a male deity from a floor excavated by Tessa Verney Wheeler at VERVLAMIVM (St Albans) in 1931 now in Verulamium Museum
The inclusion of red lobster claws makes it likely this is Oceanus 🦞

Scientists managed to extract a high-coverage genome of an extinct woolly rhino from an undigested piece of its flesh found in the stomach of a permafrost-preserved 14kyo wolf pup. 🧪🏺
One of the last woolly rhinos to walk Earth was eaten by a wolf pup — and scientists have now sequenced its genome from the undigested meat
More than 14,000 years ago, a wolf pup ate a piece of woolly rhino. Scientists have analyzed the rhino's DNA to figure out why it went extinct.

If you can substitute "hungry ghost trapped in a jar" for "AI" in a sentence it's probably a valid use case for LLMs. Take "I have a bunch of hungry ghosts in jars, they mainly write SQL queries for me". Sure. Reasonable use case.
"My girlfriend is a hungry ghost I trapped in a jar"? No. Deranged.
