If the data is there, it can be extracted, because the intended recipient was bound to have some way of extracting it. The question is how to know it's there and what to look for. For instance if you know the data is encoded in the LSB of a certain set of pixels in a lossless image, you can pull that data without the original. If you know roughly what to look for, like the data being in the LSB but aren't sure where, it's possible to run various types of pattern recognition on it. Plaintext encoded in the LSBs would be super obvious, for instance. But so would "noise" in an area of the image where LSB noise was expected to be low.

I have no idea what the state of the art is in steganographic detection, but I'm sure it involves the use of statistical tools to identify unexpected patterns in the data. Even if you used cryptography to encode a small piece of text so it became bitwise gibberish and then introduced it into a file through steganography, analytics could probably determine that the entropy of a particular part of the file shot way up. Once the data is found, the problem is no different than deciphering the intercepted message. Although steganography adds a layer of difficulty to the problem, it's just one layer. And if the trick is ever discovered, it stops being useful (to you) forever; you just have to find a new way of hiding data.

There are forms of steganography you can detect without the original, if you have an idea what patterns to look for. Ultimately the data is there somewhere.

Correcting the pH seems like a trivial problem to solve, though.

Rare earths aren't rare to begin with; they're just difficult to extract.

That's what I mean, though. Renewables belong in the conversation as part of the solution; they'll never be the entire solution. Not till we develop the tech to build a Dyson swarm, anyway.

Forget it, Jake. It's r/Futurology.

In all seriousness, though, renewables will never be able to fully satisfy demand, no matter how hard certain subs try to speak it into existence. They still belong in the conversation, and progress in better efficiency, stirafe, recycling, material sourcing, are all good to hear—but they won't ever completely replace non-renewables.

We seriously need a lot more innovation and actual development in the nuclear space too.

That's scarily brilliant.

I want to believe another 10 seconds will someday go by without this getting reposted.

In the same part of the world regularly threatened by the same toltalitarian scumbags threatening Taiwan? Less neat.

They work for peanuts.

I first saw that episode before going to bed for a sleep study. Watching Good Eats before trying to sleep is a bad idea.

Earth will be uninhabitable by then anyway.

I'm going to be a beloved supervillain. I will drive the mosquito to extinction, legalize unrestricted sport hunting of spammers, and nuke Redmond.

There won't be HOAs in the future. I'm outlawing them when I become a supervillain.
