I LOVE flight sims, mostly because the world is so damn beautiful! I spend a good chunk of my profesional life looking at aerial and satellite images yet seeing the world in full 3D, at an angle, moving, with lighting and weather just hits different.

the future could be magnificent, and you deserve a share of it
Retro-futurist propaganda poster overlooking a radiant, green utopian city of rivers, bridges, gardens, and gleaming towers at sunrise. Four people and a shaggy dog sit on a flower-covered hillside, gazing toward the city. Across the sky in huge block lettering: “the future could be magnificent, and you deserve a share of it.”

But have you considered that every problem is simple and has a single clear and obvious expression and solution/liability structure. Complexity and nuanced don't exist and/or are tools of the oppressors.

This entire argument is so vapid. Its the same form as saying we need to get from place to place therefore gas guzzlers are fine.

This, from Dennett, I wish I'd taken to heart earlier in my life. www.themarginalian.org/2014/03/28/d...
How to compose a successful critical commentary:

1 You should attempt to re-express your target’s position so clearly, vividly, and fairly that your target says, “Thanks, I wish I’d thought of putting it that way.”
2 You should list any points of agreement (especially if they are not matters of general or widespread agreement).
3 You should mention anything you have learned from your target.
4 Only then are you permitted to say so much as a word of rebuttal or criticism.

personally I think making your side of any dispute think worse for the tasty mcvibes of putting down an out group is rarely a good trade off, unless you have extremely powerful propaganda tech at your disposal or don't need your side's brains for anything later

I know this is just a "one or two feldspars" thing but I am truly surprised how many people are encountering physicalism for the first time. I thought everybody had that existential freakout as a teenager and then integrated it.

As we know from The Wire Branch the real paperclip risk is a rogue AI building a time machine and sending back a virus to modify humanity to love bent wire which ultimately results in a surprising utopia where everyone is freed from the toil of work so they can (gladly) bend wire all day.

I think there's a case to be made that you should lose tenure if you sell books. Tenure should not only be academic freedom to hold unpopular positions but to be able to change positions based on the situation. Selling books provides a financial incentive to stick to your existing position.

This is a map of the locations of at least 90% of something you can find using embeddings of aerial imagery very easily. Any guesses as to what it is? Claude Fable is completely stumped and thrashing to figure out what it might be.

I'd love to know what the "its all marketing" folks think the difference would be if the warnings were real. Hypothetically take the situation as the lab folks describe it and predict, what would be different? Labs would still arguably benefit. That doesn't mean its necessarily marketing.

I agree with dame but the difference is you can immediately assess the quality of a photo and an excellent drawing. Video games will always have room for some bug or oddity and people will say thats because of using AI because they believe AI made things are low quality by definition.

Feel like a lot of AI conversations are at about the level of someone saying "I like Wikipedia and YouTube" and then someone else saying "Oh so you're pro internet, you're an internet booster? You don't see any potential problems with the internet?"

For any new medium/domain, all personal experience by definition lies between the floor and ceiling of possibilities. No particular instance can prove the ceiling low or the floor high. They can only expand the range.

Very good vibes for GPT-6 around fiction writing, editing and interpretation. It apparently very easily and perfectly interpreted the plot and temporal structure of The Wire Branch which previous models usually only did with deliberate guidance and prodding.

You can give up basing your objections on the actual facts but if you do you won't have any basis for pushing back on glonzo against renewables.

One thing I have learned talking to lots of people about AI is that they can be both worried about the implications of AI and very excited about using AI themselves. I think people on this site tend to view many people's attitudes to AI as much less complicated than they are.

There were a lot of people in the quote tweets on this who seemed to make no distinction between using AI to develop software and including AI features in software. Don't pay any attention to uninformed opinions about how you should spend your energy.

Economics and policy are fascinating. If you want to maximise society level renewables share, what proportion of renewable energy should you require for new data centers? DC build out can reduce costs for everyone else through learning curves which is what you want....

Consider the car: a political group willing to use one will spend less of their time travelling and more of their time doing real work (campaigning, policy development, etc.) than an opponent who walks on the basis of ethical or safety objections to cars.

If there's a technology that can confer an advantage and you refuse it, all else held equal you will eventually be outcompeted by those who do leverage it. Your objections will only prevent that if you can convince your opponents, which you are unlikely to do.

Agree with Doll here for code, but for writing prose for other humans I think the inverse is true. Mainly because prose is a tool for communicating with other humans and there's no interpreter.

This is a rare book. I think there are only 8 physical copies in existence, only 5 of the first edition were ever printed. Does it matter if it gets destructively scanned for AI training?

I am surprisingly going to agree to the instruction here not to use AI to write things for people to read as a general rule with an exception: if you're going to do it dont treat it as a shortcut, recognise it takes significant effort to make it good and know its a practiced skill.

Well done Channel 4. You've really advanced the debate around ADHD through gutter contrarian framing. We are fortunate, given the last 19 years haven't been warmer than before, that we had you to warn us via the great global warming swindle.... complete shit for brains!
