Adding some personal analysis to your point, the last time I looked at plastic market research in detail, the two biggest markets by volume and revenue were packaging and insulation, which I believe were dominated by thermoplastics. Those a

Having worked in polymers and seen the development of some recyclable, 3D-printed thermosets like what's proposed here, I think this is a fair take. On the whole, I'm glad to see other researchers continuing to research the space.

An excellent question. The long-term consequences are the realm of analysis, not politics, which is why I wrote this article. Those ideas shape how politicians make decisions and which issues to prioritize. To understand how your vote may i

I'm the author, and I'm always deeply flattered when people submit my stuff. Thank you! Happy to chat more, as there was a ton of research that went into it, most of which didn't make the final cut.

The US government is dedicating something like $39B to the silicon business—is it using it wisely? Part of a series on the modern silicon foundry business, this chapter sets up the problems in the US supply chain circa 2022 that the CHIPs A

People seemed to enjoy my deep-dive on 155mm, so I'm sharing another on leading-edge semiconductor manufacturing, an industry I actually have some experience in. Please let me know if you enjoy it and want more.

I'm a huge Dan Carlin fan. I started my career as a mechanical engineer, and I have a deep appreciation for chemistry and materials science, as everything rests on that. Most of the early transistor legends were chemists after all. Hen

FWIW I have spent a few years leading GTM strategy for startups, am consulting on marketing for startups, and thinking about getting back into a startup, so I'd be open to a conversation about what you're trying to do. Fundamental

I'm delighted you enjoyed the piece so much. Honestly, I expected to get 20 views on the whole thing, as I felt like a crazy person researching this area for like 6 months. That collapsed in the belief I probably can't do much to

This was an idea I considered, but I'm not enough of a metallurgist to know how feasible it is. In a crisis, I imagine we would try lots of things, but it's easiest to start by just getting out of our own way with proven tools and

Arghhhh super embarrassing. Corrected now, I stared at this for way too long and was eager to just get it published.

Author here. In short, no, I wasn't surprised, I just wanted to cover it. I worked in 3D printing, albeit on the polymer side. On the metal side, there's been a lot of progress and 3D printed thruster nozzle assemblies are one of

I am skeptical the US would really need it in a war, but our allies certainly will. The US has air superiority and integrated combat arms. Ukraine shows how essential artillery is without at least air superiority, and they have just a few y

Just waking up to find this on HN. The points you make are completely correct. I tried to keep the focus on just US production, as I was specifically interested if there was anything I could do to help. Splitting up the process was somethin

This is a project I've been grinding on since my time with Intel. It's in an admittedly weird space - productivity software for a leisure activity - but I got so frustrated with how hard it was to give a personalized recommendatio

This is a concept I have been stewing on for a while and hadn't seen it discussed much as a potential solution or application for drone technology. It's very light on engineering, as I wanted to go for breadth and put as many opti
