I mean this is a great story, and I'm happy for this guy, but isn't this a super dirty process? Is he going to have cancer in 8 years but will have built a chip from 1971? Seems like a bad trade-off.
If you are wondering what Sam Zeloof is up to these days: he founded Atomic Semi [1] with Jim Keller (yes, _that_ Jim Keller). [1] https://atomicsemi.com/
Quite hard to grasp what they are really trying to achieve there. They are building what kind of tools, and for whom?

May I ask how you do this, specifically? What machine do you use for injection molding, and how do you make the moulds? Very interested in doing this myself. (Also interested in specific recommendations for a desktop pick n place if anyone has some)
https://www.smallsmt.biz/products/ or any similar Shenzhen special. Buy bigger over smaller. Buy, don't build. There will be a handful of recommendations for the Opulo Lumen/OpenPNP: avoid them. Avoid everything but ballscrew designs: you will spend an annoying amount of time trying to calibrate a belt-driven design and calibration will never stick. Please, do not make the mistake I did: get something with CL feeders…

I thought the entire plan of independence is building yourself and not buying at all.
I didn't build my vapor phase reflow oven, either.
I'm trying to solve my own problems, not craft a basic piece of equipment for bragging rights; I just don't have the kind of free time to have things not work perfectly.

There’s no way it’s lower cost. However what it could be is guaranteed line capacity and delivery dates. And if you’re doing small orders from a large foundry you don’t get that. Those things have value too and someone might be willing to pay a bit extra to get them. My main issue is semiconductor lines are fragile beasts that need constant tinkering. So if the system requires full time staff to keep running, that’s…
If a mask set is 50 million and you only need ten chips, these guys would only need to come in under 5 million per chip to win on cost.
500 VU19P will cost less than 5 million.

Not in Australia. Even rural is expensive.
How about the following list of 10 cities/towns in Australia with property around 100-300k AUD? https://www.mpamag.com/au/mortgage-industry/guides/what-are-...
The rest are country towns, not suburban ones. Where you need to drive hours to get to anything approaching what you might think of as “downtown”, and even then there’s not gonna be a lot there.
The reality in Australia is that the vast majority of the population lives within 100km of the east coast. It’s not like America where there are literally thousands of decent-sized small towns (tens of thousands of people), there just isn’t enough population for that. Almost half the population lives in two cities (Melbourne and Sydney) and neither of these are affordable places no matter how far out into the suburbs you go.

Usually these places are cheap because there is little economy (so few jobs), so most of the even slightly ambitious youth escape to the cities or larger towns in the area, which leaves them with ‘interesting’ demographics.
This is an interesting inversion actually, because things like meth and then the associated crime are much more of a problem in the country than the cities here, which is kind of the opposite of what you hear about the cities being dangerous in places like the US.

Live somewhere cheaper and you can make enough to have a garage by painting houses or mowing lawns.

At least three of the neighbors within sight of my own house are some sort of residential construction or property trade contractor. Two are public school teachers. At least one paints houses for a living. It is apparently totally possible to work a trade and live a recently comfortable lifestyle. I'm not saying it's easy, and I'm not saying that there is a straightforward path to break in to that lifestyle but it is evidently more than abundantly possible.
