Thanks for the link. Looks like it's the best it's been in ~2 years

Awesome read, thanks for sharing. Always interesting to read applications of Anki to those that are younger.

Some recent examples:

GPT-4o vs. Google I/O (May 2024): OpenAI scheduled its "Spring Update" exactly 24 hours before Google’s biggest event of the year, Google I/O. They launched GPT-4o voice mode.

Sora vs. Gemini 1.5 Pro (Feb 2024): Just two hours after Google announced its breakthrough Gemini 1.5 Pro model, Sam Altman tweeted the reveal of Sora (text-to-video).

ChatGPT Enterprise vs. Google Cloud Next (Aug 2023): As Google began its major conference focused on selling AI to businesses, OpenAI announced ChatGPT Enterprise.

I usually wait to see what ArtificialAnalysis says for a direct comparison.

They mention that they implemented jitter later in the post.

Great investigation. Slight aside, but I found the few typos that I noticed to make me feel better about continuing to read -- as a sign that the post wasn't AI-generated.

This is giving the "ultra-processed" term too much credit. Organic is at least pretty explicitly specified by the USDA (even if that definition is perhaps not what most people think or expect when they read the term).

Ultra-processed doesn't even have a single, consistent definition.

Many, if not most, donations have limits / requirements on what the money can be spent on. That's why it's such a big deal when someone doesn't make such a demand and says the grant is "unrestricted."

You can use non-USD currencies to judge how the US stock market has fared to avoid the issues with currency health. You may argue that dollar-denominated returns aren't real, but SPY isn't down even when denominated in EUR https://ycharts.com/indices/%5ESPXEUR

I'm not sure I'd label 20% as "overwhelming." I'm surprised it's not higher, to be honest.

Looks like Prince Alwaleed bin Talal's ownership of Fox was between 5.5% to 7% during the two-decade period of 1997 ~ 2017. He divested during an anti-corruption purge.

Here's a couple concrete examples I found. It seems like most have to rely on multiple revenue streams for it to work -- something like 1/3 reader revenue (membership), 1/3 grants/philanthropy, 1/3 earned income (events, merchandise, etc).

does that work out in their favor in the end? seems like that would really deter investment in the country. I'm not familiar with any large thai corporations.

Interesting to see the stats here. My total active library size is about the same as the author's (~50k cards), yet I performed less than 100k reviews this past year. That said, my overall retention is a good bit lower (~83%). Wouldn't have expected a 6% difference to make for a 3x higher review load!
