Why would they remain fundamentally expensive? It is a fixed machine (so eventually you recoup the investment) and running consumes nothing other than electricity and a paper gown. MRIs cost under $200 in Japan.

My feeling on geometric algebra is that you should look too much into it until you exhaust the exterior algebra. That is (in my opinion): it isn't a good use of it to replace the cross product or specialized representations of 3-d geometric rotations. It is good for when you get a bit sick of the bookkeeping of the exterior algebra. From a computer scientist point of view it is sort of adding a bit of type information beyond just vector dimension and depth of product.

Thx, but looks like you are also getting downvoted. Sorry about that.

No point up-voting or down-voting this, already flagged off the site. Possibly triggered a controversy filter? I know the title is provocative, but it is actually the point the video is trying to establish (so it wasn't just ad-hominem).

Not quite on topic. But I feel there is an issue in politics where many non-wealthy people vote as if they are "temporarily inconvenienced billionaires." That is they endorse policies that favor billionaires, as they have some hope of being one someday.

I have to say worrying about the provenance of writing has made me a grumpier reader.

For example: "The space station is made up of Russian and US segments, and there are modules from the European and Japanese space agencies too." It feels like this sentence is inserting some points, but is lacking in authorial intent. Is the intent to say the station is largely Russian and US, or to say the station has more than two partners? Probably an okay sentence, but still feels like a stone in the shoe.

This is important to think through, does one have a product, tech, tool, or even just a feature. I given thing is not necessarily at the bottom of this stack, but also not always at the top.

I know it is a video and the title is a note. But the video is plausibly claiming Github recently opted private repositories into being AI training material. And there are indeed some settings around that (though it is hard to know if one has found all such controls).

My only issue is the title. It appears they are building a replacement for GitHub of which a replacement for Git is just a component. Building a replacement for GitHub is going to need at least the sort of funding they are mentioning. So once one reads the article it makes a bit more sense.
