The social media boom has largely failed to acknowledge that at the end of the day, everything happens in the real world.

The social media tech sector is almost its own foreign nation, and it's luring the best and brightest minds away with the (fickle) promise of work-from-home and the (relative) safety of job-hopping from one wild venture to another. It's been this way consistently since the dotcom boom.

The result is severe understaffing in the jobs - college-educated, far from brute labor - most needed to fix physical problems. Welding and weld inspection, CNC machining, engineering, architecture, data science - these fields need smart people, and they're already being poached by oil companies and the military-industrial complex before the promise of a work-from-home job lining Zuck or Bezos' pockets. This leaves precious few new members in the trades needed to fix our cities, bridges and railroads.

In the promise of the Metaverse and the social media sphere writ large, it's safer to avoid the ugliness and weight and cost of the physical world and opt instead for a code-monkey 9 to 5 and Minecraft on your time off.

Worth noting cobalt is a conflict mineral, but it's a hell of a lot more affordable than platinum. This could be massive if implemented correctly. In addition to terrestrial applications, this could be huge for space-related applications where electrolysis of ice water is your primary source of oxygen.

Only issue is what to do with the brine/solids left after electrolysis.

Innovations in efficiency are always welcome, but one wonders about the downstream effects of quieter commercial drones.

The army's gonna be salivating about the prospect of spy drones that don't shriek like a giant mosquito, but anyone who doesn't want that happening at home would have cause to worry. You may also have wildlife issues if birds don't hear them coming and have a collision.

On the flipside, reducing the nuisance factor enough would make long-sought use cases like taco delivery or whatever much more tolerable.

Laments about stupid human bullshit aside, it's no easy engineering feat.

An aboveground version would mean miles of electrified track exposed to the elements; assuming constant acceleration, you'd quickly reach speeds where a single nick or bump would be catastrophic.

A hyperloop or shielded underground version is plausible, but that's miles of tunneling - and unless you want to roll the dice on some retractable wing business, it'd need to be a wide tunnel.

And that's not even getting into property/territory.

Realistically, if you wanted to go pure electro-mechanical, you could build a giant ramp up the side of the Rockies and chuck a plane off it.

Unfortunately, high-velocity speed bumps have the same effect regardless of whether or not rockets are involved... nobody would want to shotgun radioactive waste across the country.
