Attack the argument, not the person. No racism/sexism/bigotry. Good faith argumentation only. This includes accusing another user of being a bot or paid actor. Trolling is uncivil and is grounds for removal and/or a community ban. Do not respond to rule-breaking content; report it and move on.
2. All posts should contain a source (url) that is as reliable and unbiased as possible and must only contain one link.
Obvious right or left wing sources will be removed at the mods discretion. 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.

Hey, at least we have actually accomplished (edit: net-positive) fusion. 10-20 years before the first commercial plant comes online, but fusion is a technology which now exists. This is extremely awesome. Honestly, I never thought I’d see it. But, it’s here, it exists, and now the distance between today and when the first power plant comes online is just a matter of scaling the tech upwards.
Full, autonomous self-driving cabs - especially from Tesla - on a massive scale… not so much.
Er, not really with fusion actually, unless you just mean "have made atoms fuse regardless of if it generates net energy or not" in which case we've had it for decades. We have managed net energy production if you compare the output of a very powerful laser used to compress the fuel to the energy of the resulting reaction, but crucially, the laser in question isn't perfectly efficient, and only a fraction of the electrical energy put in is turned into laser energy in the beam. This means that we still don't have net electricity production, and even once we finally get that, getting the tech efficient enough to produce enough electricity to be cost competitive will be a tough ask, especially as electricity from solar in particular has been going down in price of late.
Yes, net-positive fusion was achieved in August of last year:
Scientists achieve net energy gain breakthrough with nuclear fusion
Obviously, this will take a decade or two to develop into a viable commercial energy source, but the barrier has been overcome with regards to net-positive fusion.
Its been a decade away since 80's. We should have been working on MSR and make them sustainable before getting to the next stage
It’s not a binary, not really.
We have achieved net-positive fusion as of last year. That’s the achievement we needed to move to the next stage, and it’s the one which was always a hopeful “maybe”. But we finally did it. It’s imperfect and needs to be refined and scaled up (another Herculean effort, to be sure), but we’ve crossed from the “is it even possible?” to the “we proved it can be done, now let’s make this into a practical technology.”
So, when scientists claim 10-20 years from now, it’s no longer hopeful speculation but a well-educated projection based on current development.
