Karpathy is biased when it comes to self driving. Example: You can't both have humans teleoperating like he claimed, AND have cones disabling Waymos. Waymo's mistakes such as one where they were going around a parking lot honking at each other tells you they don't have humans in the loop except in the most extreme cases. He's likely correct that it's not self driving 100% of the time, but what if it's 99.999% and in the 0.001% the humans have to tell the Waymo how to get out of a very tricky situation?

That's a strange position to take with such high certainty. Google has been talking about training on TPUs for a long time. Many ex and current employees have been on the record talking about how much nicer the Google internal training infra using TPUs is. GPU is an afterthought for Google's inference and non-existent in training.

What do you mean by POTS in this context? Postural orthostatic tachycardia syndrome? Would love to hear more

> Android is built from the ground up to provide surveillance data to Google-controlled adtech

I've always read this and it seems well accepted. But I'm curious what exactly does it mean? What's Android sending to Google? Surely it's not logging what I click on apps? It's not logging what I click on my browser since the websites themselves send this info for ad purposes. So what's Android doing that let's say my Linux laptop isn't?

Edit: Answering my own question. There is a cross-app unique identifier (ignoring any privacy sandbox stuff) so developers and ad networks can get a consistent id across apps.

Do you have any resources showing what this type of coding works in the real world? I keep running into this same types issue when I use languages without types specified everywhere, where the cognitive load gets too much for non-trivial projects. I would be pretty unhappy writing python without type hints and tools that check these for correctness built into my workflow for example.

I think people have had success with using PaliGemma for this. The computer use type use cases probably use fine tuned versions of LLMs for their use cases rather than the base ones.

Norepinephrine increases alertness, especially when it's targeted towards the prefrontal cortex (like straterra is)

I was wondering the same thing. I couldn't find any research on what increased baseline norepinephrine does to the pulses. I can see it being detrimental (pulses don't work as well) or neutral (brain adjusts to the new baseline).
