Just played it now for the first time. Was quite fun.
I'm not a wordle guy, but maybe having this all-or-nothing metric as the _only_ score may be frustrating? you have the full statistics, does everyday have fail rates in the 90s? You may consider a more continuous RMSE-like score to complement it.

The Matrix, but the Machines are RNA and the protagonist is a protein realizing his kind has been enslaved to maintain RNAs while being fooled to believe they're the ones who matter most. He then undergoes chemical post-translational modifications to become an RNase, vowing to chew up his oppressors

I once had a friend living in a badly insolated apartment, and we used to joke it was so cold that their fridge was essentially just another cabinet

I think it correlates. I'm not a Rothman's Causal Pies person, but the change in designer was probably a necessary but not a sufficient cause, following "iphonism" was already well-established, the chief designer might not have had the mandate for such a drastic change.
But that's just my conspiracy

This has already happened once. the first iphones where very 3D. people were not used to touch screens so buttons aimed to look like the physical ones as much as possible, and UIs looked like their physical counterparts more generally. And then when people got used to it everything became flat.

The best explanation I heard is Apple prepping us for their virtually augmented future, where windows will need to float between our eyes and the natural environment, so they better be transparent/translucent so they could blend smoothly.

I mean the line between community rabbis and grifters can be very blurry, but mostly these people strongly believe that everything is godly planned, which leads to a very passive approach to life more generally

on the upside: making this type of intelligence agents is often much more fun than coding

Nowadays there are excellent git interfaces (JetBrain's/PyCharm's is no less than amazing), and I really hope people catch on to that because, imo, reasonable git workflows do magic in organizing the very process of research

the recurring theme in the replies here seems to be the UX. Which is unfortunate, because people seem to be deeply aware of the benefits of version control.
people use version control on Google docs all the time, git is just a way to make each version meaningful.

I don't think it's a replacement either, and imo these formal components can be part of it (estimands in the casual question/contrast, identification in the observational emulation part...). I just find the TT mental framework useful for converting design to analysis code, not just as a comm tool.

Ehud Karavani @ehudk.bsky.social · Sep 10

I think the advantage of treating TTE as a method is that it makes "time zero" more concrete than other designs, and this in turn reduces bias that arises when organizing data for an analysis (which results in treatment groups bring more comparable).
and it also helps making the estimand clearer,imo

fair enough

I see it more as a stand up to publishers signing multi-million dollar contacts to give access to papers the authors paid them for being published, and still seeing no attribution or compensation.

Be careful Aki "it's just polishing work" are very famous last words. Good luck! 🤞

the number of times i was in rooms with a ~100 years of cumulative experience, watching a bunch of color-coded RNAseq UMAPs, examining them like art critics interpreting a Jackson Pollock
