2003, was working in a science lab, lab tech came in and said he (or maybe it was his brother) had just bought a house, really cheap, in hawaii. He said it was in lanikai estates. Family is from hawaii and I'm a bit of a geography geek, so I hopped onto mapquest to see where it was... Noticed it was due east of pu'u o'o, and I know the volcano is moving east, so I told him, look you have 10-15 years to sell that house before it winds up under a volcano. Fast forward 15 years and volcano! The volcano just snuck in under my time window, haha.

To be fair, I do not know for sure if HIS house went under; there are houses in the neighborhood that were spared.

I didn't bother to ask because when I stalked him it said he was an employee of Theranos, and I decided it was probably not a good idea to poke a hornet's nest.

Speaking of Theranos, back when I was in my 2nd postdoc (2013) we were talking about how theranos was a fraud and it was going to come crumbling down, Some other crazy short term things I predicted: Sarah Palin VP candidate, Feb 2008, Simone Giertz becoming famous (ca winter 2015). I also predicted the failure of the first starliner launch (documented here in HN). I also have managed to pick some ascendant "obscure" PLs just before hockey sticking. Used Julia professionally in 2015 (proof of use in 2017: https://www.youtube.com/watch?v=aP0Y1uAA-2Y&t=53m), used Elixir in 2017, been using Zig since 2019. And I haven't really used any other non-mainstream PLs, so I have a pretty good hit record I think. And a couple of obscure cryptos that I don't want to talk too much about.
