Max Hodak: Average Is Not Good Enough
5 beliefs, in the piece's order there

there's no one right answer, but this is a thing where you need a really defined process. There is no right answer, but a wrong answer for sure is not having something that you do very religiously as a company.

I think the best companies in my experience come from what might be characterized as scenes. There's like a moment that enables a new company to be born and there's a bunch that comes together that really creates this like unique nucleation for the new company.

And so if nobody knows how much an experiment costs, like every time you like grow up a new cell line or every time we make a new a new probe in in the fab, how much does that loop cost? Nobody knows. Therefore, experiments are free. Um, it doesn't cost dollars. It costs media. And media comes from the fridge.

Creator of the Keras deep-learning library and the ARC-AGI benchmark.
LLMs
On changing their mind
In the era of base LLM scaling (2022-2024), I believed the LLM line of research would reach a capability plateau (as later seen with base LLMs).
In late 2024, after the o3 test-time compute demo, I changed my views: the new models were showing genuine fluid intelligence, and with this new line of work, the LLM line of research could achieve unbounded capability scaling. "There will be no wall."

Their words
However, looking ahead, I still do not believe that future AI (say, in 15 years) will be based on the LLM stack. I believe it will necessarily have to move closer to its optimal, final form -- symbolic learning. Obviously this is a risky and contrarian belief -- the safe bet would be LRMs. But let's see.

we've both come to believe that when transformation fails repeatedly, it's time for something different, and one of the tools that leaders need to add to their tool belts (and probably use a lot more frequently than they do today), is starting fresh, creating new entities (agencies and departments, for example) and either endowing them with new authorities or transferring authorities from legacy institutions to the new ones.

China economy researcher based in Beijing who writes on his personal blog about Chinese political economy, history, books and music.
Li Daokui's comments are important because there are so few domestic voices in China stating what (I think) is the obvious truth about the economy: the main problem is that aggregate demand is weak, growth is running below potential and macro policies are inappropriate. This is not a novel, original or unusual insight: it's what lots of people (myself and others) have been saying for years, and is also in the most recent of the much-maligned IMF reports on China. But it runs directly contrary to the official government diagnosis which is that aggregate demand is fine and the economy mainly su… China government Related

Thorsten Frei hat einen maßgeblichen Anteil am bisherigen Erfolg der Regierungsarbeit und der Stabilität der Koalition. Die Reformerfolge der letzten Wochen sind auch sein Verdienst. Er kommt aus der Mitte der Fraktion und wird dort für das perfekte Zusammenspiel zwischen Parlament, Koalitionspartner und Bundesregierung sorgen. English, from German For the re-election of the parliamentary group leader of the @cducsubt, @Markus_Soeder and I have today proposed Thorsten Frei. Thorsten Frei has played a significant role in the success of the government's work and the stability of the coalition to date. The reform successes of recent weeks are also thanks to him. He comes from the centre of the parliamentary group and will ensure perfect synergy between parliament, coalition partners and the federal government.

In these cases I like to lean back, switch to /voice and just ramble for like 10 minutes, total mess, anything goes, full stream of consciousness.
