That's partly true but there's more to it than that.

Satellites larger than a cube sat tend to have thrusters for orbital trajectory maintenance and to desaturate gyroscopes. But what tends to happen is that since they cost so much to get onto orbit you generally want to maximise the operational life of the satellite by using as much of your fuel as possible to stay up. So most operators just use all the fuel and leave nothing to de-orbiting. And if you put it into a orbit above 600km the time taken to naturally decay due to atmospheric and orbital perturbations becomes long, 10+ years where the satellite is uncontrollable and is a hazard.

New regulations are being introduced to reduce this sort of issue but it's more of a guideline than a law so companies with a commercial interest tend to ignore it.

What this development is really good for is small cubesats which make up the bulk of satellites launched these day by over a order of magnitude. Since they don't normally have thrusters to deorbit a drag shute like this is a cheap easy way for responsible operators to keep space tidy.

This is all assuming the satellite survives it's mission to the point where de-orbiting is desired/option. Many satellites lose control to general wear and tear, radiation damage or debris strikes such as Envisat.

That is one of the bits here I would be most skeptical of. We're getting really good at text based and data based AI systems. But robotics which require operating in the unpredictable and complicated physical world are still progressing slowly.

This list is extremely impressive although I feel like it might take a little longer to map the oceans.

>2027 - Sentiment analysis: AI algorithms accurately assessed human emotions in text and speech, enabling more effective communication and customer service.

I am a little concerned about it being able to understand our emotions based on speech, so that it can tailor it's interaction with us based on what it thinks it understands about us from our emotional state.

Another one of those:

>The UN secretary general, António Guterres, said [some doomsday crap]

He's not a climate scientist, he's politician and diplomat. All this guy does for the last 5 years is giving out dramatic headlines and final warnings to the press.

No wonder many people are afraid of having kids or even too depressed to live today. Want to relax? Emergency! Catastrophe! Point of no return! Want to live? Suicidal! Grave warning! Want to have hope? "We are losing!".

Doomers' crap

so long as the product is not a commodity. if the market errs towards an oligopoly, of course those firms have pricing power. that is definitely the present circumstance, however things like LLaMa, StableDiffusion, and Alpaca are demonstrating AI (the orchestrating element) can be a commodity. in other words, if your labor is so specialized that you control the pricing power, then it's further in your self-interest to be self-employed over time. if the firm employing you provides something that compels you to surrender your pricing power, then that is a bargaining cost that will likely shrink over time as it gets commodified.

The following submission statement was provided by /u/1xdevloper:


For the first time, scientists at the University of Sydney and the University of Basel in Switzerland have demonstrated the ability to manipulate and identify small numbers of interacting photons—packets of light energy—with high correlation.

This unprecedented achievement represents an important landmark in the development of quantum technologies. It is published today in Nature Physics.

Stimulated light emission, postulated by Einstein in 1916, is widely observed for large numbers of photons and laid the basis for the invention of the laser. With this research, stimulated emission has now been observed for single photons.

Specifically, the scientists could measure the direct time delay between one photon and a pair of bound photons scattering off a single quantum dot, a type of artificially created atom.

"This opens the door to the manipulation of what we can call 'quantum light'," Dr. Sahand Mahmoodian from the University of Sydney School of Physics and joint lead author of the research said.

Well this is a change didnt know about the slaves before now you do

Elon himself has backed the emerald mine up so idk where you getting it’s fake from It’s very well known to be true

America is filled with apiring people and hard working ones has been for well over a century

We invented nukes the most terrifying weapons in existence We’ve created cures for many diseases

We’ve created diseases worst then anything god could make and I’m not even religious

Net positive definitely won’t be done other then earth applications space costs a fuckton and has infinite potential

Takes a fuckton to even tap into that potential though

Didn’t hate worship him just pointing out the fact one of humanities greatest chances for space exploration their main leader is a toddler

If that’s hate worship to you you definitely a child because I could go a lot worst then that have you been on the internet long?

And hope is definitely a better word because there’s very little chance it gets far enough fast enough

But it's still not original thought, nor thought at all but emulation. It can never transcend its inherent limitations which are dictated by the source of its creators. I have no doubt it will progress to the level of godlike power but it's intelligence is still missing something vital to sentience. Something about us that is not quantifiable.

Again, it lacks a soul, life force, whatever you want to call it.

I hate to say it but humanity is way too selfish and fractured to tackle this problem together. We are going to have a much hotter planet in a couple of years so we better learn how to deal with it.

Yeah I’m being a Debbie Downer but realistically we need to start thinking how we live in a hotter world and save as many people as possible

My original comment was about the the renewed hope in space. I was expressing excitement about the new horizons we can achieve.

So, thanks for really bringing down the vibes, bro. I'm well aware of Elon's alleged past (from what I've heard, the emerald mine hasn't really been backed up). Either way, I'm ignoring Elon and focusing on SpaceX. The company filled with aspiring people in both leadership and in employees. They began the company with the dream of revolutionising humanity's perspective of space and they've more than achieved that and they're still achieving more. That's impressive and rare in these times. I think, (maybe hope is a better word) SpaceX will provide a huge net positive for this planet, and I eagerly wait to see where we will go.

There's my little speech done. I'm done with Elon and his shit. I just don't care anymore. Just because I'd wasted time idolising him in the past, doesn't mean I'm gonna spend the future hate-worshipping him. It's boring.

It will also be used to by governments to predict who might be potential opposition. Even many years ahead. There is a youtube video with that story line, where they use drones to kill anyone who is might become a potential opposition leader when they are still students.
