Admittedly a half baked idea, but I wish someone was attempting to design an ornithopter as an alternative to drones for things like short-distance deliveries. Given higher power density batteries and advances in RL to find efficient flight control policies it seems plausibly possible, and it'd eliminate noise pollution concerns almost entirely. Plus, the mental image of a mechanical harpy eagle (payload capacity greater than body weight) perched on your window sill with your doordash is just too appealing to pass up.

Space elevators.

avmich• 3 years ago

Space elevators aren't compatible with existing and planned satellites.

Edit: let me explain. The space elevator necessarily goes to the height of the geostationary orbit, ~36000 km above Earth surface, and placed on equator on the Earth. It will intersect all orbital planes of satellites, and vast majority of satellites flies below GEO. Satellites orbits are not quite predictable in practice, due to fluctuations of forces acting on satellites, so without active avoidance system - which almost all existing satellites lack and new satellites aren't planning to have - eventually satellite will collide with the elevator, at speed which seems to be rather catastrophic to both satellite and the elevator. There were many attempts to solve this problem, but I haven't seen an adequate one so far, and I rather doubt the humanity will replace the satellites with the space elevator (which won't be able to launch long-term satellites for the same reason). So, space elevator won't actually work as intended.

Home printable chips. Its getting harder and harder to trust the hardware built by Intel/AMD etc to be backdoor free.

Democratizing chip manufacturing technology where one could print something at even 10x the cost would be tremendously helpful, for activists and those who speak truth to power.

Sam Zeloof's new company Atomic Semi might be up your alley: https://twitter.com/atomic_semi

abdullahkhalids2• 3 years ago

I am sure this company will help advance technology. But not sure if they will ever release anything publicly, which is what is needed - open source designs for the "chip printer" and for the actual chips as well.

These guys had the right idea https://libresilicon.com/ Though it looks like work has paused for quite a while now.

Affordable housing

gameman144• 3 years ago

Isn't this one of the more funded "moonshots" that exists today? Or is this mostly commentary? (Or are there specific untested kinds of affordable housing you'd want to see developed?)

logicalmonster• 3 years ago

Minor personal pet peeve: I really hate the term affordable housing. Yes, housing can and should be less expensive. But there's a lot of stuff surrounding housing that needs to be addressed beyond just the actual cost.

To me, the way homes are designed is often backwards. For instance, they're often designed from the outside-in rather than from the inside-out. Instead of starting with a room you want to build and making it the best possible layout for a specific function (say watching movies, or hanging out with friends and talking) houses are often built from the outside-in: they'll usually start with the shell first and then roughly pencil in an area that can be called a "living room" but there's no real care in designing spaces for optimum functionality.

And the way that homes can be laid out relative to other homes can be improved. What about concepts like pocket neighborhoods? Would they work everywhere? I don't know, but they seem like they would be transformative to a lot of peoples' lives.

There's plenty of affordable housing. It just might not be in the perferred location or with preferred attributes.

A system addressing population distribution to adequately balance areas with an excess and deficit of housing would be good. As would something to influence housing preferences, like size and amenities.

Massive voter engagement. Like 90% voter participation.

giantg26• 3 years ago

Can we add a caveat for knowledgeable/responsible voter participation? Many of the people I know who don't vote are completely unaware of stuff that's going on in the world. And many people who do vote don't do so in the primaries and just vote party line in the general election. This limits the variety and balance of viewpoints since it's mostly controlled by the party leadership and extremist views are more represented in primaries due to motivation.

How to write correct software. With software eating the world, it might be a good idea that the software eats correctly, without bugs.

nextos• 3 years ago

This is one of my favorite moonshots.

The problem is that it is hard to monetize, so it should in principle be funded by grants and not by VC.

bick_nyers• 3 years ago

I'm very hopeful that AI will be able to bridge this gap. Even if 100% correctness is too difficult to describe for most projects, being able to stand up 99%+ coverage in a matter of minutes with AI test generation would be game changing.

Fair tax. Today rich people/corps have many loop holes for avoiding tax. If that was fixed globally, individuals could pay less.

giantg26• 3 years ago

I think we can all agree we want fair taxes. What that looks like varies by perspective. It would be interesting to see a system or tool that makes everyone think it's fair.

precompute• 3 years ago

"moonshot" is conservative for the following, but still:

- YOLO and let the economy crash fully for once

- Tempering the "line always goes up" attitude in computing tech that has mostly destroyed enrollments for other hard science / engineering courses

- Some sort of global communal breakthrough to render the lack of community participation / "I have friends but they're over there in the good guy lands" obsolete

- Successful, affordable DIY modular robotic assembly line

- Banning all aerated / carbonated / flavored drinks

- Robust, transparent, privacy-respecting media fingerprinting BEFORE AI content vomit takes over the internet

- Good-faith online shamanism (the truth is out there!)

- Transitioning the Earth and its inhabitants away from water-based energy sources (we split atoms to heat water to make electricity to heat water, etc). It's easy because it's THE universal solvent, but changing the input material makes all the other steps alien and (hopefully) less challenging for the environment / other humans to assimilate to.

Career alignment tools based on aptitude and interest.

It seems there's a very small number of people who like their job. All the aptitude stuff today doesn't seem very helpful. I wish I knew what I would be good at so I could stop hating my job and be successful.
