Rocket propulsion tech. Not just because of SpaceX, but I really hope we develop newer and more efficient propulsion techniques.

WRT F150; I am so upset with the state of the auto market when it comes to pricing. Manufacturing margins are enormous when it comes to cars. The F150 is no different. A two seater (effectively) vehicle stamped out of metal and plastic should never cost as much as those things do. I hate car companies and their pricing models.
Look up the chicken tax bill that passed a few decades ago that basically stopped any foreign car manufacturers from selling pickups in the US. That's why trucks are so much more expensive than other types of cars.
Web Assembly It's interesting in a bunch of ways, and I think it might end up having a wider impact than anyone has really realized yet. It's an ISA that looks set to be adopted in a pretty wide range of applications, web browsers, sandboxed and cross platform applications, embedded (into other programs) scripting, cryptocurrencies, and so on. It looks like it's going to enable a wider variety of languages on the web…
I want to believe... I always thought WebAssembly had a lot of potential, however, in practice it doesn't seem to have turned out that way. I remember the first Unity demos appearing on these orange pages at least 4 or 5 years ago, and promptly blowing me away. But, after an eternity in JavaScript years, I still dont know what the killer app is, technically or business wise. (Side note - I encourage people to prove m…
Example of WASM being used in a major product:

You can infer from this that it's making them 3x faster than anything a competitor can make, and probably inspired a lot of those 'Why is Figma so much more awesome than any comparable tool?' comments I remember reading on Twitter months back.
Self-driving cars. Now that the hype is over and the fake-it-til-you-make-it crowd has tanked, there's progress. Slowly, the LIDARs get cheaper, the radars get more resolution, and the software improves. UE5's rendering approach. They finally figured out how to use the GPU to do level of detail. Games can now climb out of the Uncanny Valley. The Playstation 5. 8 CPUs at 3.2GHz each, 24GB of RAM, 14 teraflops of GPU,…
> The Playstation 5. 8 CPUs at 3.2GHz each, 24GB of RAM, 14 teraflops of GPU, and a big solid state disk. That's a lot of compute engine for $400. Somebody will probably make supercomputers out of rooms full of those. Mmm, this sounds like exactly what people said at the time the PS3 was going to be released, and I can only recall of one example where the PS3 was ever used in a cluster and that probably was not that…
The PS5 and Xbox One X are commodity PC hardware, optimized for gaming, packaged with a curated App Store.
Sony also won’t just sell you hundreds or thousands of them for some kind of groundbreakingly cheap cluster. They will say no, unless you’re GameStop or Walmart.
Everyone with a high-mid-range PC already has more horsepower than a PS5 and it’s not doing anything particularly innovative or groundbreaking.
The PS5 is going to equivalent to a mid-range $100 AMD CPU, something not as good as an RTX 2080 or maybe even an RTX 2070, and a commodity NVME SSD (Probably cheap stuff like QLC) that would retail for about the same price as a 1TB 2.5” mechanical hard drive. It is not unique.
Data center servers optimize for entirely different criteria and game consoles do not make sense for anything coming close to that sort of thing. For example, servers optimize for 24/7 use and high density. The PS4 doesn’t fit in a 1U rack. It doesn’t have redundant power. Any cost savings on purchase price is wasted on paying your data center for the real estate, no joke. Then when the console breaks you have to pay your technician $100/hour in compensation, benefits, and taxes to remove and replace it.

I'm kinda sad for you - I've been using and advocating zerotier for a while (it's amazing and indispensable)...but in my circles the word 'wireguard' has got people excited, which (anecdotally) is benefitting tailscale and generating more hype around them than zerotier ever got. Hopefully a rising tide will lift all ships and you find a way to capitalise on it :) (I prefer device-based zerotier-style access rather th…
We are doing fine and V2 is coming soon with a ton of improvements. I just have to occasionally point out our existence again. The pulldown showing other devices on a network does look spiffy but that wont scale. We have users with thousands of devices on a virtual LAN and the protocol will scale far larger. Not only will that not fit in a menu but any system that relies on a master list will fall down. That list and…
I think the website could do a better job showcasing how it's used.
Hope my feedback is helpful and wish all the best!
VR. It seems just about ready, but still a little too expensive. While good games are obviously already there, I'm more curious about work. Would an infinite desktop with an appropriate interface beat the reliable old 2x24" screen setup I have? I think it could.
Sidewalk delivery robots. The problem is a lot easier that driverless cars (everything is slower and a remote human can take over in hard places) and huge potential to shake up the short-to-medium distance delivery business. It's the sort of tech that could quickly explode into 100s of cities worldwide like escooters did a couple of years ago. Starship Technologies is the best known company in the area and furthest a…
When you eventually grasp it, makes blockchain look like we took took a wrong turn in 2008.
