It's more like BEV reality. They (car manufacturers, oil & gas, etc) have been trying to get hydrogen to work for ages now, but BEVs have made much more progress instead.

Hydrogen fuel-cells: Everyone (consumers, manufacturers, etc) has been waiting for this to come into mass-production and used in cars. Hasn't happened yet.

Hydrogen combustion engines: Good idea, but still not as feasible at sounds. I've heard of problems with efficiency of the engines, dangers in storing and transporting the fuel, leakage, etc. It still hasn't happened to scale.

Hydrogen production is still very energy and CO2 intensive. The small amount of hydrogen that can be produced using green methods or with carbon-capture, should be used towards planes and rockets.

BEVs won't be a cure all for every machine on earth, and not immediately either. But over time, it should become the most cost-appropriate solution if you factor in the cost of emitting CO2 and other GhGs.

For "intent recognition", I agree. A system trained on data of mostly black committing crimes might flag more black people with ill intent.

But for the sake of identification at security checkpoints, if a man named Omar - who has an eerie resemblance to Haani the terrorist - walks through the gates, then they probably need to do a more thorough check. If they confirm with secondary data that Omar is who he says he is, then the system needs to be retrained on more images of Omar. The bias was only that they didn't have enough images of Haani and Omar for the system to make a good enough distinction. With more training, it will probably be less biased and more accurate than a human.

Oh no. No social media site should ever claim that a post, story, or image is legit.

For some viral pics/posts, it should probably show a warning that the image doesn't have any signatures, no valid signatures, or a revoked signature. Otherwise, it probably just shows a verified signature chain, for example: BleedingHeartInfluencer*[edited]* → NyTimes*[edited]* → AP*[story]* → AhmedMohammed*[photographer,2023-12-03]*.

We can always assume nation states and other powerful people will know how to fake images, GPS, reality, etc. We can also always assume fakes will still be shared by many people without any proper authentication.

The main goal here would just be to reduce proliferation.

The video of the injured girl is a behind-the-scenes clip from a movie. Way to fall for your own propaganda:

Sorry, this needs more clarification! Do you mean "intent recognition" where some AI, trained with biased data, will assume that some brown person is upto no good? Or do you mean that they will misidentify black and brown people more often due to how cameras work? Because the latter has nothing to do with biased data.

You need to follow trusted sources like the IDF

I can't even tell if you're being sarcastic or if you actually believe this.

Ofcourse you should trust the footage from the US forces fighting in Iraq or Afghanistan because they're backed by a democratic government and wouldn't carelessly cause collateral damage, shoot innocent civilians, torture detainees, and then jail the whistleblowers. /s

Well, not necessarily. How about just embedding the following in the EXIF tag: digital signatures from the original camera; digital hashes of the original image; digital sigs for the publisher and the article where the pics will appear.

Any additional processing by a "social media content creator" - for example, adding captions to make a meme out of it - will also include the prior chain of digital sigs and hashes.

Now when it pops up on social media sites/apps, there can be little info bubbles that link to the original pic or article, or provide info on ownership of the camera along with date and timestamps of the pics.

Garbage will always exist on social media, but at least we can have these little tools to verify authentic images.

Hydrogen is a dead end, because it is nowhere near green to produce it in large quantities, and the technology is still not ready, nor is the supply network. It's just an idea pushed by fossil fuel companies hoping to transition to selling hydrogen.

E-fuels are not zero emission, but the basic premise is that somewhere else along the chain it reduced GhG emissions into the atmosphere - like capturing methane from cow burps, or biogas from garbage dumps.

These fuels will have uses - hydrogen in rockets and e-fuels for aircraft - but for almost all land vehicles, BEVs or going electric, is the most readily available and working strategy.

Nobody disputes it when social media addiction is the topic du jour, but internet porn addiction has been around even before social media became big. And I'm basing this on the number of downvotes you got - I guess these are all the people that went on Pornhub, saw nothing enticing, and moved on.
