Nature is awesome.

Some birds in the already insane birds of paradise species have been found to have "ultra black" feathers specially evolved to suck in the maximum light particles. The purpose is to create a backdrop for a colorful display f feathers that will really pop against the black.

I love the part where the males are seen as doing this so they don;t actually have to work as hard to produce truly brilliant colors. Lazy men.  :P

Work smarter, not harder, man.

So you're saying men are smarter than women?

This is obviously a technology application that will make life better.  :P

Except they are just cameras. The recognition is done remotely.
The UK was using b&W video cameras and 1/2" portable VTRs in 1960s.
Now, for several years they have been using computer storage and facial recognition at carnivals and music festivals. It's probably illegal. The retention is.
The car number plate recognition is the same technology, just needing a smaller database and less CPU power, used on a toll road here for over 11 years. There is actually no AI involved. Just human curation of a data for a database in a datacentre, though marketing & PR calls it AI, Deep Learning, Machine Learning etc. It's just an incremental development of 1980s pattern recognition.
It's lightweight cameras, radios and improved Mobile data coverage that allows individuals to use it. The headup displays for text on your "glasses" is a gradual miniaturisation of 1960s fighter pilot headup displays that were projected on the cockpit window from a very bright CRT.

Sooooo.... Y Combinator has moved from funding AirBnB to funding a way to backup your brain... the only catch is that it kills you.

That made me cringe at the thought of invading someone’s memories.

Nectome saying at end they want to learn from the brain’s  wisdom?  My cynical self asks if nobody learns from history or the genuine wisdom of philosophers why are they going to learn wisdom from some random brain? Not as though they can preserve a genius brain and keep it in on-going working order as in a horror story.

The thing is the brains have to be fresh. So you sorta have to die specifically for it to happen.

Also it won't actually ever work. I know the long biochemistry reason, apart from the philosophical & faith question is "you" purely  a function of your brain activity.
It's one of the most annoying tropes in SF since 1990s approx. Simply lazy egotistical writing, as are most AI characters and "nano <something>" to fill plot holes that are just magic by another name.

In other news, Voice recognition is much worse for women (and they don't really know why), also it's not AI and not much different to 25 years ago.

On positive side, practical fusion is closer due to improved electromagnets. Without surrounding the vessel with radioactive waste from conventional nuclear, which does already give net power out. The neutrons of the fusion accelerate fission in the waste to make enough heat to generate steam for the turbine.

Efficient fusion would be actual magic.

Not sure how long it will take, but all the theoretical physics say that it should work. There is no scientific reason why it wouldn't. Might still be a good way off, but when it comes it will be the biggest thing since the steam engine. Maybe even even bigger than that.

The steam engine was known for hundreds of years, maybe two thousand before it became commercial. Then it was nearly two hundred years to become efficient.
It was deeper Cornish tin mines that made steam driven pump economic. It was VERY inefficient. This is why steam was used on inshore vessels long before ocean going ships. The efficiency was too low so enough coal couldn't be carried. Also the extra expense of fuel overcame awkwardness of sail on rivers, lakes, harbours and replaced horses on larger canals.
The steam turbine was a MUCH older idea than a piston engine. Obvious too. Modern Steam turbine was used in 1884 for electricity and in early 20th C on ships, though for a while the US Navy switched back to pistons.
https://en.wikipedia.org/wiki/Steam_turbine#History

>>
So we are not doing badly on Fusion. The first designs were only about 65 years ago and there is a way already to make net electricity which makes regular nuclear power station waste safe.
Hardly anything is overnight.
Idea of transistors was 1890s, theory was 1930s, working lab device 1948, first all transistor radio about 1955 but not common till 1959. IC idea is 1954, but not common till 1970s, the first microprocessor very quickly after, but wasn't till about 1975 good enough for PCs (which predate IBM PC by 6 years).
Smartphone idea is 1970s. Prototypes in 1980s, first models in 1998. But it took Apple's deal for data with selective operators to make it popular in 2007 (they didn't actually make first with touch screen or invent anything in reality for it. The GUI was bought in. Main chip was Samsung, no Apple phone chips, iOS created from MacOS X which was from UNIX based NextStep). ARM core of smart phones first used in Acorn Archimedes about 1986 and Apple Newton (development started 1987 and shipped in 1993)
Capacitive touch screens are as old as resistive. Resistive was needed for resolution for handwriting recognition, sketches & notes. Newton, Palm etc. Apple abandoned it on iPhone because it was aimed at consumer, not business who wanted to annotate documents on phones & PDAs, not an innovation but a change of use from information creation to content browsing.
Tablet computers were a niche success from 1989. It took combination of better LCDs, LiPoly batteries, faster ARM CPUs and large Flash memory to make them practical for ordinary consumers about 20 years later. Also Linux / UNIX proved to be a better OS for them than Windows (iOS is derived from BSD UNIX and Android is a layer on top of Linux).

Incremental developments before widespread retail success. Same is true of Video tape, Video disc to BluRay, MP3 players (Apple iPod very late to that party).

Some developments are like SF in concept and only see short lived application, or even just demos:
Holographic storage
Bubble memory
Magneto Optical disks (nearly popular in 1990s, too expensive).
Laser Discs (a technical dead end in started in 1970s, never really took off outside USA).
The 8 Track Cartridge had low penetration outside USA. Doomed by 1963 Compact Cassette, called such as RCA had a 1/4" format cassette in 1958.

Rare nano tech mechanical displays like SF:
DLP projectors. Each pixel is a moving mirror
eInk. Each pixel is black balls in a cell of milky liquid.
Mirasol. A colour panel using mechanical cells like petals on a butterfly wing to do colour. A market failure. Used in three eBook readers last made in about 2012.

OLED tech predates real LEDs. Took a long time to get it viable. LCD is only monochrome. Uses a backlight and stripe dye filters for colour. The material concept for LCDs dates from 1880s. It was 1970 when workable displays made. It's only about 10 to 15 years ago that colour panels have matched CRT for quality and still only more expensive systems.
