A hydrogen fueled engine would not produce CO₂.

The word “quasi-intellectuals” is accurate. I’d even go as far as calling them pseudo-intellectuals. Very few people here know what they’re talking about. That goes for you too.

That's the point. Lillium is also battery powered. It will have minutes of runtime in all likelihood.

Which would basically be conventional aircraft but running on biofuels or syn-fuels.

All VTOL aircraft have the same issue: Insane energy consumption. There's a reason why quadcopters have flight times measured in minutes, and why helicopters never came close to displacing small aircraft. This will be no different.

Absolutely not. Airplanes have to be aerodynamic, and it would be incredibly challenging to make the entire bottom portion of the plane something that can open up and fit a giant battery. Never mind the weight of the whole system plus batte

Long-distance battery airplanes are literally impossible. If you don't agree with hydrogen powered aircraft, you are advocating for conventional airplanes forever.

So basically "more war" is the killer feature. Some see this as a total failure.

Worth pointing out that Dennard scaling has long since ended. Architecture design is just as important for reducing power consumption as the process node. Arguably, even more so.

The author is not doing a good job of differentiating ordinary ray tracing with path tracing. It is path tracing that actually gives all of those wonderful render effects "for free." Ray tracing by itself isn't that impress

Lithium batteries are extremely flammable. Worse, fires are extreme hard to extinguish. For trains this would be a truly huge fire. Converting methane into hydrogen is known as steam reformation. We can easily due this, but we don't wa

Java was heavily pushed by Sun Microsystems. I’m not sure if it was ever in the same boat as the languages mentioned in the OP.

Give it another decade. PWAs will only get better and more integrated. PWAs could still kill off native apps eventually.

Probably the big one. All the critics of it assume everyone will be a millionaire-adjacent or better and have home charging. In reality, the vast majority of people need fuel.

We can just make them thicker so abusive bending is not easy to do.

I wonder how long before some group of manufacturers comes out and say “Ah fuck it, just make a new connector with a new baseline level of performance!”

Well I was counting on NAND flash. That's how are getting more transistors per chip with them. The memory cells have basically stopped shrinking in NAND and actually got bigger when we first started to stack them. FinFETs effectively l

Even for transistor density, it isn’t quite true. The transistors aren’t getting any smaller like they use to. A lot of growth now involves stacking transistors on top of each other. 3D transistors lets you pack more of them closer together

Potatoes are a lot more nutritious than rice though. Plus being easier to grow and in far more places. You also have to include things like maize, sweet potato, squash, etc.

I'm going to make a rather blunt argument that the difference was the arrival of New World foods, allowing for much larger populations than was possible in China at the time. We have had too many civilizations supposedly "came clo

Fundamentally, nuclear needs to be subsidized, just like other green energy projects.

The problem is that batteries are bigger and heavier than engines.

We live in a world where absurdly powerful VLSIs sell for a just few hundred dollars per unit. You don't need to think very hard to realize that all of that stuff cost next to nothing to manufacture.

Because we have no way of machining extremely precise parts with modern technology at a low cost...

With finFETs the transistors are not physically getting smaller anymore. Instead, by making taller and taller finFETs, you can squeeze the transistors closer without actually having smaller transistors. By some definitions, you can say Moor

We will run out of batteries if we want to power every car on Earth with them. We will go with hydrogen instead because it is not going to run out.

It’s currently on an upward slope, due to shortages of raw materials and components.
