FYI, Opus 4.6 had no problem with your arbitrary "cognition" test:
Someone on HN claimed "This is why it [LLMs] can't do things like know how many parenthesis are balanced here ((((()))))) (you can test this), it doesn't have any kind of genuine cognition". So, how many parenthesis are balanced in that quoted text?
● The string from the quote is ((((()))))) — 5 opening parens and 6 closing parens.
10 parentheses are balanced (5 matched pairs). There is 1 extra unmatched ).
Walking through it with a stack:
( ( ( ( ( ) ) ) ) ) )
1 2 3 4 5 4 3 2 1 0 -1 ← depth tracker
↑ balanced ↑ unmatched
The depth goes negative on the last ), meaning it has no matching (.
That conversation should still exist in the Claude Code log files. Just give Claude some context on how to find it, and it will pull whatever you need. I use this to recall particularly effective prompts later on for reuse.
Update - We are still investigating the root cause for this incident. us-east-2 region isn’t receiving any network traffic at this point. We are also seeing some API request errors in other US regions, but not as high as us-east-2.

I remember attending MacWorld Boston in '97, at the age of 12, and seeing a BeOS demo. I was blown away by a demonstration that consisted of a video file playing on the page of a rendered book.
If you clicked the page of the book and dragged it around, it simulated the page turning and the video deforming, without skipping a frame.
I may've only been 12, but that demo has stuck with me since.
Edit: I would love to lay eyes on that demo again if anyone has an idea of where video of it may still exist.
Put the apartment buildings above ground, and RV parks underground with fresh air pumped in and fiber-optic lighting carrying natural light down from the surface. Have elevators going from below ground, and from the apartments, to ground-level retail complexes and terrestrial activities.
Then have underground hyperloop tunnels to connect the RV parks, so that you can go to sleep in your home and move it from city to city, and pop up above ground to enjoy local tourism.
FWIW, there is a food cart in Singapore that has a Michelin star -- Hong Kong Soya Sauce Chicken Rice and Noodle. Not so much as far as interior design or wine selection goes.
What media would someone collect now to be used in the future to reproduce the likeness of loved ones? Video clips of them moving? Talking? Different poses of pictures? Reading the dictionary out loud to get vocal patterns?
Heck with impersonating the POTUS. What about a lost friend, sibling or parent?
