We have an actively updated blocklist, which you can see here: https://lemmy.world/post/2246130 if you feel like any website is missing, contact the mods. Supporting links can be added in comments or posted seperately but not to the post body.
3. No bots, spam or self-promotion.
Only approved bots, which follow the guidelines for bots set by the instance, are allowed.
4. Post titles should be the same as the article used as source.
Posts which titles don’t match the source won’t be removed, but the autoMod will notify you, and if your title misrepresents the original article, the post will be deleted. If the site changed their headline, the bot might still contact you, just ignore it, we won’t delete your post.
5. Only recent news is allowed.
Posts must be news from the most recent 30 days.
6. All posts must be news articles.
No opinion pieces, Listicles, editorials or celebrity gossip is allowed. All posts will be judged on a case-by-case basis.
7. No duplicate posts.
If a source you used was already posted by someone else, the autoMod will leave a message. Please remove your post if the autoMod is correct. If the post that matches your post is very old, we refer you to rule 5.
8. Misinformation is prohibited.
Misinformation / propaganda is strictly prohibited. Any comment or post containing or linking to misinformation will be removed. If you feel that your post has been removed in error, credible sources must be provided.
9. No link shorteners.
The auto mod will contact you if a link shortener is detected, please delete your post if they are right.
10. Don't copy entire article in your post body
For copyright reasons, you are not allowed to copy an entire article into your post body. This is an instance wide rule, that is strictly enforced in this community.

It sounds like things are going well for this guy and that is great and all, but how much would we honestly expect to hear if it wasn't going well?
This story is circulating all the media outlets and feels more like PR than a legit example of how this procedure is actually going to work for most people.
Given how eager people are to pounce on negative news about anything Elon Musk-related, I expect we would be hearing way, way more about this if it wasn't going well. "Elon Musk's Neuralink Damages a Man's Brain!" and "Elon Musk's Neuralink Fails!" Headlines and such from every rooftop.
Can't we just fling him into the sun and let someone else take over these companies?
That takes an immense amount of fuel. We orbit the sun at 30 km/s, of which you have to cancel about 24 km/s to actually hit it. This is after escaping Earth's atmosphere (another 11 km/s of delta V) and effective sphere of influence which takes even more fuel. We could use some gravity assists off the moon and inner planets to get there, but even then it's not really economical. Our best bet would be to send him out super far using ~9 km/s of dV, and then use a very small amount to cancel out any remaining angular momentum and let him slowly fall into the sun. Unfortunately, as with all efficient space maneuvers, you pay for them in time, and this maneuver would take you 3 years. We'd have to somehow support the little bastard all that time but it might just be doable.
We could just set him up for a one-way orbital rendezvous with his car and be done with it...
Can you imagine if he got there and realized he left his keys at home?
If we get him outside of the atmosphere and throw him in the direction if the sun, he won't eventually get caught in it's gravitational pull?
You can get caught in the sun's pull by just leaving Earth's sphere of influence, but remember that all of the planets are already caught in the sun's pull and have remained distinctly outside of the actual sun for essentially forever
That's why I suggested shooting him directly towards it, wouldn't he just keep going unless he somehow manages to hit something on the way there? Surely he'd end up hitting the sun?
He'd still have the 30 km per second (67,000 mph) of sideways velocity that Earth has when it's orbiting the sun, and that speed is enough to prevent Earth from ever hitting the sun.
Orbits aren't very intuitive; if you want something you launch from Earth to fall straight into the sun, you actually need to fire it directly opposite to the direction that Earth orbits in. So if you imagine Earth orbiting clockwise, you want to shoot the thing counterclockwise. If you do that at the right speed, you counteract all the orbital speed and the thing just falls into the sun.
If you can speed something up a completely unlimited amount then sure you could aim straight at the sun and just fire it so fast that it hits the sun anyway. It'll be off-centre a bit but the sun is pretty big. Consider how much of the sky isn't sun though. If the sun is directly overhead and you shoot straight at the sun, the thing you fired is already going 30 km/s sideways before you even started. We could do the trig to figure out how fast you need to shoot it to still hit the sun anyway but I think the more important part here is getting a feel for the motion involved.
How about if you leave the earth's atmosphere first, come to a stop, then fire him/accelerate directly at the sun? Or I guess just leave him there so he falls into it slowly? I'm not trying to be difficult or anything I'm just interested.
Depends on what you mean by the "come to a stop" bit. Stop relative to Earth? You're still going Earth speeds relative to the sun, which is what you're trying to hit. It's like throwing a ball at something while driving past it. If you mean stop relative to the sun then sure, you don't even need to shoot him towards the sun, he'll fall right in. The trouble is that stopping relative to the sun is specifically the bit that takes a lot of energy.
Cool, thanks for the info, it's very interesting. I, for one, vote for trying it with Musk, even if it goes wrong he won't be here anymore.
Even if we fail, Elon Musk ends up further away than he currently is
