I get where carmakers are coming from though.

Cars used to compete on distinctions between driving experience/fuel economy/reliability/etc. In comparison, differences between electric cars is mostly superfluous. They're very interchangeable.

For the next generation of car buyers, infotainment and features are going to be the main features. And if you are handing all of that away to the tech companies, your entire company is going to just become another captive hardware partner of the tech giants.

There's no moral argument against ripping DVDs one way or the other.

There's a civil/economic argument: arguably copyright/intellectual property make for stronger societies that produce better stuff for everybody.

But there's nothing immoral about copying or watching something you came across. The author isn't injured by it- nobody is. Except, like I said, perhaps society in general.

While you're at it add the USBC power hack https://github.com/vk2diy/hackbook-m4-mini

I've been traveling for business with this as my sole machine for 3 months straight and it has proven to be an excellent system.

Wonder if anyone is looking into splicing those spider silk genes into a fungus. Maybe the mycelium could gain enough tensile strength to hold pressure? Maybe exude the proteins and form strong tubes around itself? Fungal structures are already surprisingly light for how strong they are.

What I don't understand about the proposal is that every c-c bond the fungus could make still has to be shipped from earth.

I would say alphafold is to structure prediction as crispr is to gene editing.

Crispr did not solve gene editing either, but has been made accessible to the broad biochemistry and biology researchers to use.

Both similar impact and changed the field significantly.

Entire fields are based upon the existence of crispr now, it demonstrated its impact. It has been 2? 3? years, people who were making papers anyway have implemented AlphaFold, it hasn't exactly spawned a new area.

This is true: i.e. they use rare metals not rare earth metals.

On HN, I hope we can share a correction like that respectfully: after all, they gave good info, except for a one-word slip of the tongue.

The critique seems to extend beyond correcting that error, becoming confrontational, questioning motivation and honesty with phrases like "supposedly worked in." and the long bit defending lifespan and enviromental impact against people who "don't seem to have a problem with oil drilling, fracking, coal strip mining, etc" - they didn't even touch on that subject.

Thank you for responding, I agree with your points, I did indeed make a mistake.

My two cents having formerly worked in perovskites trying to upscale the process:

Perovskites are exciting (or were exciting) because they have a high theoretical efficiency, are relatively simple to prepare, and the "worst" component in them is lead (an incredibly abundant material). The big problem with them is that they are famously horrifically unstable in ambient conditions.

Roll-to-roll processing means that you can fabricate them in mass scale. Ambient means that they claim to have solved issues like working in glovebox conditions.

Even if the price of solar panels has come down below labor, the fact that they are produced from rare earth minerals goes (in my opinion) underreported.

Consider the relationship between perovskites and multi-junction solar cells similar to the comparison between sodium and lithium ion batteries. Lithium will always have a higher capacity, but sodium is so abundant that for many applications it just doesn't matter anymore.

https://www.sciencedirect.com/science/article/abs/pii/S09500...

They produce 60-80 milligram of calcium carbonate 'per fiber', per 30 hours. I'm interested to know how they keep the bacteria alive over time, through the concrete curing process (high temperatures, high level of carbon dioxide, making any liquids in the vicinity highly acidic), and how the bacteria remain viable over time. Concrete we consider to last over decades, or a century?
