New comment by thimabi in "Google Flight Simulator"

I hadn’t thought about that, it’s a valid use case and likely to have increasing demand as drone deliveries become commonplace in the next few years.

Very convincing indeed! I really want to know what AI made that, as I’m looking forward to creating personal/customized music in a similar way.

I wonder why Google doesn’t bother competing with Microsoft in the flight simulation niche. All that Google Maps data would be pretty cool to use for that purpose, but instead we’ve got only this toy feature inside Google Earth.

I disagree. I’d prefer if my government invested more in AI solutions, so as not to depend so much on foreign technology.

In an ideal world, Brazil would have a thriving private sector, capable of competing even in the AI sector. Unfortunately, that’s not the case, and I believe that without government action such endeavors won’t really succeed.

I wouldn’t describe what happened here as incompetence. As a “carioca”, I am pleasantly surprised to know that the government’s IT department is involved in AI work — even without the budget to create its own models from scratch.

That “Don’t Insure Me” option hidden in the middle of a country list is pure evil. I’m used to seeing dark patterns everywhere but that’s a first for me.

From where I stand, it’s not fair to charge the hell out of people who fall for these tricks while giving steep discounts to the ones who don’t. Maybe there’s a “fool me once” aspect to Ryanair’s shenanigans, so at least their impact might be limited somehow.

New comment by thimabi in "Confidential submission of draft S-1 to the SEC"

thimabi — Tue, 09 Jun 2026 02:15:54 +0000

Not OP but, anyway, AI output should be treated like any other source material.

I study from reputable sources every day and never cease to be amazed by how many errors or misconceptions they have. Peer-reviewed articles, books from renowned scholars, news from major publications… regardless of the source, false information and contradictions accumulate. I’d wager that AI, besides helping me uncover these issues in the literature, has had a lower error rate than most of the materials that I read on a daily basis.

New comment by thimabi in "How OpenAI delivers low-latency voice AI at scale"

thimabi — Mon, 04 May 2026 20:03:25 +0000

> Voice AI only feels natural if conversation moves at the speed of speech […] At OpenAI’s scale, that translates into three concrete requirements: Global reach for more than 900 million weekly active users

Surely the number refers to the total users of ChatGPT overall, and the fraction of those who use voice features is considerably smaller, is it not?

That’s the kind of thing that influences business decisions like knowing how much hardware and software optimization to throw at a problem.

Extremely high!

Those various caveats there — “value-aligned”, “safety-conscious”, “case-by-case agreements” — probably mean that no project ever will be “worthy” of OpenAI’s assistance.

In the unlikely event that an abiding project appears, then yeah, sure, it’s very probable that OpenAI would assist it :)

Five-figure minimum spend sounds pretty expensive for the vast majority of businesses out there. Of course, just a drop in the bucket for major brands.

Will we also see a GPT-5.5-Codex version of this model? Or will the same version of it be served both in the web app and in Codex?

I don’t understand why these bets are allowed at all. Can one just make an account there and bet in anything?

The whole “prediction market” charade is increasingly proving to lend itself to abuse. I hope regulations catch up with it soon, otherwise more shenanigans will follow.

New comment by thimabi in "John Ternus to become Apple CEO"

thimabi — Mon, 20 Apr 2026 20:59:08 +0000

I also liked the part about growing the company while reducing its carbon footprint by more than 60%.

Even if that figure might somehow be inflated, it is impressive nonetheless.

New comment by thimabi in "Tim Cook to become Apple Executive Chairman. John Ternus to become CEO"

thimabi — Mon, 20 Apr 2026 20:54:41 +0000

I don’t closely follow the news about Apple and now I’m wondering why they decided to go forward with this change at this moment.

As the world undergoes increasing supply chain issues, wouldn’t it be in Apple’s best interest to keep Tim Cook as CEO for a while? Or is he the one who’s looking to transition to a less demanding position?

Meta does both. It has long been said that businesses have little organic reach in Meta’s platforms, as an incentive for them to use ads.

> I'd prefer to see board (or executive) level signatories over lay employees -- the people who can enforce enterprise policy rather than just voice their opinions

Although it would be nice to have some high-level signees there, I think we shouldn’t minimize the role of lay employees in this matter. Without having someone knowledgeable enough to build and operate them, AI models are worthless to the C-suite.

> The Department of War is threatening to […] Invoke the Defense Production Act to force Anthropic to serve their model to the military and "tailor its model to the military's needs"

This issue is about more than the government blacklisting a company for government procurement purposes.

From what I understand, the government is floating the idea of compelling Anthropic — and, by extension, its employees — to do as the DoD pleases.

If the employees’ resistance is strong enough, there’s no way this will serve the government’s interests.
