>We don't exactly program AI, do we? It's mostly black box.

It's not a black box - you can add restrictions and modify if you haven't made the world most unreadable code of course.

Current ai is all math based ultimately following patterns and probabilities and bunch of other stuff, maybe so is the human brain but not so simplistically as a computer does it... if you got a good grasp of the math you can adjust it as you need such as prevent your ai from saying outrageous things which we have seen ChatGPT being adjusted by Microsoft when it was added to Bing for example. And the training data you give it also limits what you will get.

​

Ai can't really create something new entirely, it will only create a mashup of pre-existing data in such a way that it appears new but its really just putting pre-existing things together in a new way (this is how image gens work using patterns).

The end result might not be what you expect because of the amount of variables involved but you can collect lots of data to see how it got there and adjust. The end result however is still always limited to its programming. You can never get an ai to break out from its core programming..for example an Ai that generates text isn't suddenly going to produce 2D images and an image generating ai isn't suddenly going to ask you how your day was.

I have never liked the term "Artificial Intelligence" as it's become commonly used because it's really not true. AI is nothing more than a few complex algorithms layered on top of each other. The black box you speak of is simply the general inability of humans to intuit why the combination of algorithms, given a set of data produced a certain result. Think of AI as programming where the results are non specific. I watched a video the other day where someone wrote a language model and trained it for 24 hours on only the works of Shakespeare and it used it's algorithms and fancy maths to try and predict what the next word should be to sound the most like it's training data. That is non specific. Specific programming would be taking the works of Shakespeare and splitting out every sentence, and writing a function that chose 3 random sentences and output them as a "new" paragraph.

I also saw a video where someone trained a language model on the whole of 4chan to create bots for a short time and it was exceedingly convincing.

From the article:

> Liu also noted that wormholes would magnify objects differently than black holes do, meaning scientists could distinguish the two. For example, microlensing via a black hole is known to produce four mirror images of the object behind it. Microlensing via a wormhole, on the other hand, would produce three images: two dim ones, and one very bright one, the authors' simulations showed.

As someone who has actually coded for A.I, I can tell you that we are far from Skynet. However, it will vastly improve our knowledge because computers are great for finding correlation between data sets, but absolutely suck at finding causation.

I recommend learning to code, as computers, at least for now, need humans to give it common sense.

The learning part of AI is based on/similar to how neurons learn. Once an AI has learned/been trained it stores data and filters for it on the hard drive.

How does a brain work? Data is written in neuron clusters (scientist have been able to find neuron bundles representing concept). The filters are neural connections coming out of those bundles. Brain optimises performance by strengthening commonly used connections and removing old unused ones.

Tained AI + continuous learning algorithm = basic brain even if only comparable to an insect.

Vertical farming itself is very practical because it avoids land erosion, nutrient depletion of soils and limits harm to nature. Besides that vertical farming can increase yield, nutrient density and taste through a controled environment (I.e. nutrients, light, etc.). It also needs no pesticides because of that controlled environment. Vertical farms also require about ⅓ of the water needed for conventional farming and a lot less land.

It has already been tested on multiple different vegetables, beans (soy beans for example) and leafy greens and it works for all of them. Some require different versions of vertical farming.

The major problem with vertical farming is it's massive energy consumption and expensive construction and maintance. Everything has to work perfectly for it to have optimal results.

The fun part of vertical farming is, that we can also try ourself with GMO in a safe environment, without worrying that the new strand will spread.

Certain food, especially potatoes will be hard to farm in large quantities inside an urban environments and we will still need farm land for it. Just less.

We also need to get away from eating meat as one the largest uses of farmland is for animal feed production.

3/4 of the sub is terrified of technological change, and wants a moratorium until we "figure it out," chuck capitalism, get a UBI, kill the rich, something or other. A lot see every technological change in the most gratuitously dystopian way possible. But when you think the rich actively want to kill 99% of humanity and every new advance will either give them the opportunity, pretext, or idea, I guess it follows. But doomers and tankies get to exist too, even if I disagree with them completely.
