I’m honestly surprised Apple didn’t retire the Siri brand.

At this point, “Siri” has a pretty strong cultural association with being underwhelming or unhelpful. Even if the new version is dramatically better, convincing people to give Siri another shot may be harder than launching the same technology under a new name.

Feels like a missed opportunity to reset expectations.

I would assume that the outcome probability of people selling other companies to buy Anthropic/SpaceX/OpenAI has been priced in already.

I do imagine they get an insane amount of reports, i guess they haven’t figured out how to filter through them all

I miss those days. Oregon trail was the first game I played on the computer in 1993 (there was a computer in our Kindergarten class).

Nostalgia for the old web - building websites in HTML on Angelfire and Expage.com. Learning programming on visual basic and how to copy and paste <marquee> to welcome people to the site and to sign the guestbook…

Very surprised to see SpaceX valued higher than OpenAI.

Isn't there some alternative approach? I.e when someone submit ai slop they get a strike. Three strikes and you are suspended from submitting to the bug bounty for x months/years?

*Edit - I get it. It seems like the authentication is a challenge.

I wonder if movie theaters ever thought to have "Free" movie tickets before a certain time on certain days. They would probably make money just on the popcorn sales since most of these theaters are empty during the day.

User how old is the earth? and how do we know? who determined it

talkie-1930 The earth is at least 80,000,000 years old. This conclusion has been arrived at by geologists, partly from the study of stratified rocks, and partly from the consideration of living organisms. Strata have been formed, quietly, one upon another, in many parts of the world, from the earliest times down to the present day; and the thickness of some of these strata amounts to several thousand feet. Now, it is plain, that a long period must have elapsed, during which such beds could be accumulated. Then, again, certain living species have continued unchanged from the beginning of the stratified formations up to now; and, as no such species have become extinct, it is argued that the earth must have existed, at least, from the first appearance of these organisms. In round numbers, we may say, that the earth has been a globe, fit for the habitation of living beings, at least 80,000,000 years.

Yes. It was great for when I had a major surgery last year and had a bazillion questions for the surgeon. But I don't always remember to. My parents definitely don't even think about it.

I think the post conflates two issues:

1. AI-generated charting. 2. The existence of a reliable record of the visit.

I am skeptical of the first in some cases (i.e. bias), but strongly in favor of the second.

My father is 80 and has Parkinson’s. He routinely leaves appointments unsure of what the doctor said, what changed, or what he is supposed to do next. Even when I attend with him, we sometimes disagree afterward about what exactly was recommended.

This happens with pediatric appointments too. My wife and I occasionally remember instructions differently: medication timing, symptoms to watch for, when to call back, whether something was “normal” or needed follow-up.

That is a care quality problem, not just a convenience problem.

The risks are real: privacy, consent, retention, training use, liability, and automation bias. But those argue for strict controls, not for a blanket refusal. Make it opt-in, give the patient access, prohibit training without explicit consent, keep retention short, and require clear auditability.

I do not want opaque AI quietly rewriting the medical record. But I also do not think “everyone relies on memory after a stressful 12-minute appointment” is some gold standard we should preserve.

ARC-AGI 3 is missing on this list - given that the SOTA before 5.5 <1% if I recall, I wonder if this didn't make meaningful progress.
