2020's - 70%

2030's - 93%+

This may seem insane to many, but my reasoning for why we can have such advanced tech so quickly is simple. We will be building 10 000's to 100 000's of narrow super AI's. In late 2020's there probably will be such net designed and fine tuned just to control the position of atoms during assembly process(I posted such net here few days ago, but what I mean is net able to control assembly process of something large like car, not just few tens of atoms), other nets to take care of real time quality check during "printing" on this atomic scale, ultra complicated patterns for macro scale things, atom by atom will also be designed and imagined by AI. And all these nets will have trillions to quadrillions(or more) of parameters.

This is assuming super AI won't emerge during the next 7 years.

What I would print...in post scarcity world, obviously our culture will change drastically. People will also change. We adapt and are getting used to new advanced tech very quickly. I don't think I will be into printing stuff I don't really need like cars, tons of gadgets. We could exprience all of this in ultrarealistic VR.

I would probably print stuff that can keep me in shape, great and diverse food, things that will be necessary to keep me in good health(regeneration pills or liquids), basic necessities like some 2030's era toothbrushes, soap (if we will still use them).

Ocasionally some nice things which I can give as a gift to friends and family.

If tech will be so advanced that we will be able to survive even accidents in space, I can print some small spacecraft and travel around our Solar System(if law will allow for such thing).

But more likely I will connect with like minded people via future version of internet and we will "Crowdfund" larger more ambitious projects which will need large, industrial scale printers, not small garage versions for personal use.

So let's say 200 000 people will get together to create a project to for example build some cool, large scale undewater city or large artifical city/hotel in space, or huge telescope. Stuff like that.

Again, for many it may sound like 2100's tech, but ultra advanced narrow AI's will accelerate our progress at least 1000 fold. More likely billion fold or more. New materials, new, powerful compact propulsion systems etc. It can all start and be ready by the end of this decade.

It Delivers Near Perfect Linear Scaling for Large Language Models

"they", you mean we, we(literally you, me, other people here) may be behind this simulation.

The memory requirement is greatly diminished because of their system-algorithm co-design approach. When compared to cloud training frameworks, the suggested methods significantly reduce memory use by over a factor of 1000 and a factor of 100 compared to the best edge training framework can discover (MNN).

This framework saves energy and encourages practical use by decreasing the per-iteration time by more than 20 compared to dense update and vanilla system design. Their findings show that small IoT devices may make inferences, learn from experience, and acquire new skills over time.
