The cost of sequencing a human genome has fallen over 100,000 fold in nominal terms since 2001.
In a new visualization, I've added some of the key advances in sequencing during that timeline:

New working paper: nowcasting using regression on signatures!
We introduce a new method of nowcasting that uses mathematical objects called signatures. Regression on signatures subsumes the linear Kalman filter & is more robust to disruptions in data series 😍

If I can tell someone hasn't hand-painted the graphs on their slides instead of using software, it taints them and makes them look sloppy and cheap.
To me, it sends a message that they don’t care enough about what they’re communicating to put in their own effort and make sure it’s correct. If I can tell it’s AI, it doesn’t “liven up” slides, it taints them and makes them look sloppy and cheap.

Those of us giving talks on generative AI 😬
I don’t know if anyone else notices or cares, but when I see a presentation in which the speaker uses obviously generated-AI images to illustrate their slides, it makes me immediately less confident in whatever other content they’re presenting.

Hey #econsky,
We keep hearing about ticket resellers being a problem. Artists charge $ and resellers use bots to buy tickets in bulk, selling them for $$$.
What if econ can help? Here's one little trick to stop ticket resellers.

Just yesterday I was on a panel with colleagues from @bankofcanada.ca & @banquedefrance-off.bsky.social and we were discussing the risks of central banks NOT being multi cloud / only using a single provider. I didn't expect to have such a clear example of how those risks could crystallise so soon.

Is the Reform MP who says she’s driven mad by TV adverts full of Black & Asian people a racist or realist? How many migrants would the Tories expel? & should the UK be selling fighter jets to Türkiye?

But the way we get time use data hasn't changed much. Could AI open up radical new ways of collecting it?
