question?Why do people get seasick, and what mechanism in the brain causes seasickness, and how can a brain surgeon cure seasickness through brain surgery?

Okay.

So seasickness is actually pretty straightforward mechanically.

Your inner ear has this fluid-filled system that detects motion and balance, right? When you're on a boat, there's a mismatch between what your eyes are seeing and what your inner ear is telling your brain about motion.

Your brain gets confused by that conflicting signal, and boom, nausea and dizziness.

Now, the brain surgery part is way more niche.

There's actually a real procedure called a ve-

A lot of websites now include captions and transcripts.

Screen reader technology has improved massively, and there's far greater awareness of the need for accessible design.

Major platforms have built-in features for people with visual, hearing, mobility, and cognitive disabilities.

That said, many websites and apps still lag behind.

Poor color contrast, missing alt text, inaccessible forms, that sort of thing.

And the gap between what's technically possible and what's actually implemented remains pretty wide in lots of places.

I'm just wondering, is there any data as to where we are with accessibility now, like how much web is accessible versus 15 years ago?

Everyone has seen the memo about the paper usage, right?

Zora, I know we make a lot of jokes here, but I am not going to lie, that memo was one of the most dispiriting things I have ever read.

How do they differ?

Good question.

So Anthropic's approach is basically about building AI that's helpful, harmless, and honest.

But they do it differently than OpenAI.

They focus a lot on safety research and understanding how AI actually works under the hood, rather than just slapping guardrails on top.

They believe in being transparent about what they don't know and won't pretend to be an expert when they're not.

That honesty thing you noticed, that's kind of baked into how they train me.

Someone told me, like, just making it past 10 puts you in the top 10%.
