M4 Mac Mini Gaming in 1440p vs. 1080p
The M4 Mac Mini is fine for casual gaming so for more graphically demanding titles you’ll likely have to dial back to Medium on graphic settings and play at 1440p or 1080p. Here’s how they compare. #gaming #macmini #shadowofthetombraider Subscribe to CNET on YouTube: Never miss a deal again! See CNET’s browser extension 👉 Check…

They will have to adapt. Just like humanity has done before.
This is not going to replace everyone overnight so there is plenty of time to adapt just like the automobile replaced horse carriages and the light bulb replaced candles this is only going to make our lives better and people need to adapt or be out of work.
That sounds harsh but only because you have worked in a job for 30 years that doesn’t give you the right to slow down technological breakthroughs.
What you are essentially saying is that you are arguing for the waste of human resources only to keep doing anything in an inefficient way to use as much human resources to build things as possible since you want to have people keeping those inefficient jobs.
The results are in. Just look at the Soviet Union and their system of having people work any job just to have them officially having a job.
Let the people adapt to the market (people exchanging goods on a voluntary basis for their own benefit) and you will see that people will find other jobs and the world will be a better place and we eventually will go to Mars.
If you try to keep technology outdated with government interventions just to keep the status quo as it is – well then we are likely going to Gulag – not Mars.

Yelectric

isNull isNotNull that’s the secret sauce :D. Maybe there’s a chemical process on their alloy or they do nonlinear 3D printing. They print concentric rings and one has a higher tolerance between when it cools down. Enough to turn, not enough to let some liquid methane through. Hard, but maybe possible?

There is a reason why tanks are made of sheet metal.
It is stronger, lighter, uses less material and energy, has a lot better surface finishes, is uniform thickness, does not have voids and stresses, are faster and cheaper to make, and so on.
Also the clip of the powder laser sintering printer and the part coming out of it highly polished is fake. That kind of process gives a mat pretty rough surface finish.
isNull isNotNull
August 14, 2020 at 3:02 am
My understanding is that the tanks in rockets built by “traditional” methods were never made of sheet metal. The tanks were built from solid formed pieces of aluminum alloy, and a cnc machine removes material to form a latus framework inside the tank to save on weight while minimizing compromising rigidity. This leads to a lot of waste in rocketry over what normal industry has to deal with. So what may work for rockets, might not be practical for say, cars, or propane tanks.

@Shandor Ai already create music, people faces or landscapes that didn’t exist, new shapes for industry, it also decide you could be your friend on facebook, what you could like on Tiktok, play chess or over games better than humans, pilot army planes etc
Skypper SC

Shandor

Skypper SC: Ai music and art are crap and you should be able to tell. It can’t pilot a plane as well as a person, because that’s a ton harder than chess. As for algorithms on Facebook and the rest, they’re so stupid that they show me ads for stuff I already bought! If they had brains or common sense, the programmers would have them offer me cheaper or better alternatives!

@Nick West no that’s called being uncomfortable. If it were a woman, I’d feel the same way. Too much eye contact can make some ppl feel uncomfortable.
DLKreationZ
February 6, 2021 at 2:35 am
@Nick West did you just learn that word? Because I saw you commented the same thing on another post that just said it was “next level”. Are you throwing it around to get engagement from other users or is there another agenda? Because you can’t just use any word in any conversation. That’s just embarrassing.
Nick West
February 6, 2021 at 4:55 am
@DLKreationZ Life must be really hard for you if watching two people have a conversation and making eye contact is “uncomfortable.” I made that comment twice because ridiculous men like you have the audacity to make comments about two men making eye contact in 2021, on a video for a company that is literally 3D printing rocket components. Some people are just incapable of making progress. 🤦🏻♂️

We’ll see, right now I can’t find any space oriented sources that are talking about this rocket. Only mainstream media (not that that’s bad, just that it’s weird that space oriented media seems uninterested). So I’m not hopefull, but happy to be proven wrong spaceX did what everyone thought was impossible not that long ago (and still pushing boundaries).

First, the cash register was born, obliterating the abaca and cash handling of the past. Then the cash register evolved, requiring people to work the checkout line. A few decades 1980s the bar code evolved to be standard. Now, we can pay without even swiping a card or paying in cash with a simple swipe of the of the hand. Even further, self-checkout was introduced and when I first saw one , I thought it was a joke But, self-checkout has evolved to be successful and proliferated into increasing standards and many retail stores are adopting this marvelous trend. As we become more and more automated as a society, retail competition gets more and more strained. Many local stores feel the pressure and end up closing down. Larger retail stores have immense supply chain options that can crush locality businesses as they heavy weight themselves into your cities, automating everything to the point that you don’t even have to leave the house to live anymore. Everything can be ordered online and delivered in some cases cheaper than the locality stores that carry the same thing.
Oh damn not sure what I did there my bad, that was a huge rant. 😤😂 my point is automation is going to ruin many careers in the next 2 decades.
