I feel like an attempt at that was already on the big "Machine learning fuckups" list, where a group in China tried to predict who'd be a criminal based on pictures - but of course their dataset just compared company ID pictures vs. mugshots, so they came up with a very advanced algorithm for determining if a person was clean-shaven and wearing a suit.
I went to look at these dipshits to try and figure out if they're all actually thirteen years old. But no. It looks depressingly familiar:
They have one science person - a molecular biologist - everyone else is some kind of "multiple start-ups business guy!". Their "thechnologist" (what) is listed on LinkedIn as an "entrepreneur". Skills: "Entrepreneurship." No qualifications listed. And their CTO is running five companies concurrently.
basically a bog-standard collection of "innovators" who will raise hundreds of thousands of dollars for tech that at best simply doesn't work, at worst is actively destructive to society, then get out once the share prices start to drop and list it on their resumes as a phenomenal success.
the main thing that bugs me is the company has been around for like five years, it's seriously worrying that they haven't gone bankrupt yet. Then again, they don't appear to have any actual technicians to pay.
Hundreds of thousands would be optimistic, honestly. Theranos raised tens of millions with equally impossible claims.

The earth is going to die because a not insignificant portion of our population are full on sociopaths and for some reason we give them all the money

yeah I'm hopeful it's just vaporware and they're just scamming some clueless investors out of money
the worst thing would be if they actually created some kind of semi-functional guesswork prototype and some police department tried to use it
Have I got the deal for you! Tamahagane circuit boards! This ancient Japanese metal is what makes samurai swords cut through anything!
Tamahagane printed circuit boards do away with basic tin, copper, silver and gold! In its place we use tamahagane metal which makes your electrons move so fast they cut the wind!
Get on the cutting edge by putting our crappy bog metal in your servers today!
The ‘tamahagane’ steel used in traditional weapons may be the perfect material to cut through asteroids.
Anime is good
This sentence makes me irrationally angry.
The actual details seem good!
In a paper detailing early experiments, the team – including Genrokuro Matsunaga, a 70-year-old swordsmith and Takeo Watanabe at Kanagawa Institute of Technology – explain how they have made several rock corers with various metallic compositions. Four contain tamahagane, the traditional metal made from iron sand and charcoal that is used in Japanese swords. “To achieve the sharpness and plasticity demand of the corer tip, we borrowed the techniques of traditional Japanese sword-smithing in fabricating the corer samples,” the authors write. (You can view stunning images of this process in our gallery: The amazing craft of samurai swords.)
Matsunaga used iron sand from a beach in Japan, melted it down and tempered it to make the tamahagane. The process involved heating the metal to searing temperatures and then cooling it rapidly, over and over again.
The resulting corers are small, cylindrical devices with a bladed edge angled inwards. Instead of swiping a katana sword at the asteroid – which would be cool but impractical – the idea is to launch the tamahagane-tipped corer at the space rock at great speed. In theory, it will dig into the asteroid and allow for a sample to be scooped up. A tether back to the mothership spacecraft could then reel the device and asteroid fragments in.

Then you read the rest of the article to find that they haven’t actually tested their actual handmade-artisanal rock corners because they’re too expensive.

It annoys me because tamahagane is
A) really inconsistent composition wise
And traditionally closer to cast iron
This is, in fact, why they have to fold it so much, because it's needed to spread out the carbon content and remove the impurities. Not to make it amazing steel, but because the original steel is so crap that you have to spend a lot of extra time just to get it even close to modern high carbon steel.
Additionally, the process of heating and rapid cooling is "hardening". Tempering involves very controlled heating well below the melting point and then allowing it to cool down in the air over time. If you rapidly heat and cool, you'll form marstenite, which isn't necessarily bad, but it's brittle. You have to temper it so that it will not just shatter on impact.
I need to harden steel in a forge, but I can temper it in my kitchen oven.
My problem is that this appears to be entirely a vanity project for Japan, and it's being treated like it's an advancement without actually answering why this is supposed to be better than the more controlled modern methods using better steel.

Instead of steel folded 10,000 times, give me a really good croissant
I'd settle for like a single burrito from Chipotle folded competently.
No. You will take burrito that is somehow simultaneously folded too loose to stay together, and so tight the tin foil is all scrunched up in the center.
