BloombergNEF says solar could become the world’s largest electricity source by 2032 as global electrification accelerates

​

BloombergNEF’s New Energy Outlook 2026 says rising electricity demand, energy security concerns and rapid electrification are accelerating the global transition toward renewable energy. The report projects solar could become the world’s largest source of electricity by 2032 as countries invest more heavily in batteries, grids and electrified infastructure.

For reddit


If humans 1000s of years ago had contact of some sort with Greater Beings, what else would they be besides ET?

(sorry about the "for reddit" thing; copied over from a pages doc)

Lets assume that in the future, ET contacts us.

If there is truth to religions of a cosmic sort, Beings and Kingdoms and Realms etc- what else would those things be?

That is the scientific explanation to religion.

I keep seeing people say that ET wouldn’t be religious because they are too smart and rational for it- as if ET wouldn’t have an even greater understanding of the universe, have theories about things humans can’t even think about, have spiritual experiences, have spiritual longings,  and maybe even have “texts” or artifacts from some older, greater, now apparently gone species.

As far as the cosmic beings in human religions, if the stuff is at all real- what else would it be besides ET?

Many extinct species never went extinct.

This may be mostly about semantics, but it's about perspective and science too.

At least some of the time, a species said to be extinct was never wiped out and never died out.

At least some of the time the gene pool of a species doesn't stop reproducing. It just slowly changes until the genes reach a critical point and the organism is another species- a lot of the time a species that is said to have gone extinct actually continued on, slowly changing into something else.

Sometimes a whole species- and it's long-term offspring- are destroyed, like in a cataclysmic event, but many of the species we say are extinct kept passing their genes down and down, with slight alterations (up until the present sometimes), and eventually the old genes changed enough that a new species is made from an old one.

I understand evolution is messy and that all sorts of genetic lines move in all sorts of and multiple directions, but that's my point. A species that doesn't exist anymore can also, a lot of the time, be said not to have disappeared, but simply changed into something else.

Humans and whatever comes next will be that way too. We won't go extinct. We'll just change over time until either we all spectate into different things while some pockets or variants stop existing, or both humans as we know them now exist along side other offshoots of ourselves.

Below 5nm, copper interconnects get worse the thinner they get. A topological semimetal that looks 20× worse in bulk is beating them at the nanoscale.

Something I've been chewing on for a while, and I think it deserves more attention than it's getting outside the materials press.

Everyone tracking advanced nodes already knows the interconnect bottleneck is the quiet ceiling on scaling. Transistors keep shrinking, but the wires connecting them don't shrink for free... Below a certain dimension, copper stops behaving like copper. Grain boundary scattering and surface scattering start dominating, the effective resistivity climbs sharply, and the barrier/liner stack you need to keep copper from diffusing into the dielectric eats more and more of the cross-section. At sub-5nm linewidths, copper's effective conductivity can collapse into the 10⁶ S/m range. That's roughly an order of magnitude below the textbook number people still quote at conferences.

But...

A 2025 paper in Science (Khan et al., from Stanford) on niobium phosphide thin films showed something I keep going back to. NbP is a topological semimetal: that is surface states are quantum-mechanically protected against scattering. In a thick piece of NbP the bulk conducts worse than copper. Substantially worse, like 20× worse. So in any normal context, you'd dismiss it.

But because the surface conduction is protected and the bulk isn't, the ratio flips as you go thinner. The surface stops being a correction term and starts being the dominant channel. At around 1.5nm, NbP films hit ~3 × 10⁶ S/m. At that thickness, copper is below them. Further, the NbP films don't need to be single-crystal. That's a big deal for anything resembling a real fab process, because epitaxial growth on patterned wafers is a nightmare and one of the main reasons exotic interconnect candidates never escape lab demonstrations.

I want to be careful here. This is one paper, sub-5nm, on test structures. It is not a process. There's no integration story yet for liners, no etch chemistry, no reliability data, no EM lifetime, nothing about how it behaves over a few hundred thermal cycles next to low-k dielectric. The gap between "outperforms copper in a measurement" and "TSMC qualifies it for N2" is roughly the size of a decade and several billion dollars. Anyone who's watched cobalt's partial, awkward arrival as a local-interconnect material at the leading edge knows how slow this actually moves. Ruthenium has been "next year's thing" for several years.

But I am an enstustiatic when talking about developments and what makes me think this one is worth tracking anyway is the timing. The S&P Global 2026 outlook has copper consumption from data centers alone roughly doubling between now and 2040, from ~1.1 Mt to ~2.5 Mt. That's mostly because of busbars, power distribution, cabling, but the interconnect copper sits inside the same supply chain pressure, and it's the layer where the physics is breaking first. If the most advanced nodes are forced into a partial materials substitution at exactly the moment the rest of the grid is also competing for chip-grade conductors, the supply picture isn't going to look like the current projections.

The broader thing I keep coming back to: when we talk about "replacing copper," we're usually talking about four totally different problems that get collapsed into one: aluminum at bulk scale, CNTs in weight-critical applications, architectural workarounds like sodium-ion or HTS cables, and then this nanoelectronic regime where copper hits hard physical limits. The fourth one is the smallest by mass but the most interesting by leverage. A few grams of NbP in the right layers of a leading-edge chip could matter more, strategically, than a kilometer of aluminum cable.

What will happen if we reach singularity?

I saw an article today saying we could possibly reach singularity within the next 4 years or something. I didn’t really know what this meant so I started looking it up and it kinda seems scary? What do you think would happen if we reached singularity, would it be a good thing or a bad thing?

This newly developed technology is successfully turning carbon dioxide into 110 pounds of daily fuel

​

Researchers have developed a new catalytic system capable of converting carbon dioxide into usable fuel at industrially meaningful scales, reportedly producing around 110 pounds of fuel per day during testing. Scientists say technologies like this could eventually help recycle captured CO2 into cleaner fuels for sectors that are difficult to fully electrify, including aviation and shipping.

If life can be silicon/boron based with ammonia as its medium rather than water, we may already know where it lives

I've been building a speculative framework for a non-carbon life form and I want people to tear it apart.

The entity I'm calling SBSC — silicon, boron, sulphur, chlorine — uses ammonia the way we use water. The actual living thing is a crystal lattice. When ammonia evaporates it doesn't die, it goes dormant and waits. Like a tardigrade but made of minerals. When ammonia returns, it wakes up.

There's a variant called SBSF where fluorine permanently locks the lattice. It never goes dormant again. It just slows down with temperature. It's effectively immortal.

The uncomfortable part: Enceladus has confirmed hydrothermal vents, silica, ammonia, sodium chloride as a chlorine source, and molecular hydrogen. That's most of what SBSC needs to exist right now. NASA keeps calling it promising for life as we know it. What if we're looking for the wrong life?

The bigger question: if this chemistry is simple enough to have emerged at the birth of the galaxy, what does a 4 billion year old version look like? Our definitions of life were written entirely around carbon and water. Is that a description of life, or just a description of us?

What new “human jobs” do they create alongside the automation?

The automation of prospecting and top-of-funnel outreach by BDR and SDR AI tools won’t eliminate the work force but it is going to mean a massive restructuring of the sales team. Watching the ads with Jordan Belfot talking about ""firing"" BDRs to focus on ""closers"", but the broader market is seeing this as the emergence of highly specialized human roles to manage and leverage this AI ""workforce."" My point is, instead of just fewer people, the roles will shift. You’ll get people managing the AI itself, prompts, data, making sure it doesn’t go off the rails or sound like spam. You get more technical sales roles building the system behind the scenes, wiring workflows and CRM so everything actually runs. And then you’ve got closers focusing purely on high-value conversations because the pipeline is already there. So it’s less a thing of humans vs AI and more the fact that the middle layer of reps doing repeatable tasks is going to be the one getting squeezed the hardest. And then …. specialized roles will emerge around it. Stay with the program and you’ll be fine. Or?

Data centers, computers, T.I.s, A.I.s, and the internet ALL THAT

A species, such as homo sapiens, will be altered or relegated by things like these data centers.

Humans are not the same thing they were 50 years ago. And soon they won't be what they are now. They won't mean what they mean now, they won't have the same position in the universe they have now, they will be less than their own creation.

THERE IS NO WAY THAT HUMANITY, AS WE KNOW IT, WILL CONTINUE TO EXIST.

Hopefully, humans will be OK in the coming regime.

Be good ya'll..

Don’t use the taxis…

I think we should use our experiences with advancements of the recent past to be wary of future ones.

Remember when Redbox was $1? Then everyone flocked to Redbox and Blockbusters shut down and a Redbox turned into $10?

Maybe I’m a Luddite, but I was in Vegas and saw these strange robot taxis driving people around. When I asked my taxi driver about them he told me they were free…for now. When everyone abandons the human taxi drivers who knows how much they will charge. Worse, what jobs will the taxi drivers have? One of the best parts of traveling for me is talking to the locals and chatting with the cab drivers. Idk I hate this timeline and it is soul crushing. I’m having a hard time imagining what the future will look like and how to prepare my kids for it.
