When you no longer have angency or ownership over your own capital, it’s not capitalism, it’s feudalism.

Okay so how are you going to filter all the water in every water shed, pond, lake, estuary, etc?

We could start with just stop cutting down the old growth ones that are still left

Oh yes, the entire heating/cooling system is quite a beautiful bit of engineering. a very elegantly designed “supper manifold” and heat exchanges that can push or pull heat from any device to another in the vehicle. They don’t even have heating elements anymore, they just run the motor less efficiently to produce more heat!

That’s my point really, we just commercialized everything, and introduced a bunch of extra steps. Could argue it enabled us to scale and handle very large amounts of people residing together.

It’s funny how as we increase a nations gdp, and general wealth, we commodify everything. day care, dog walkers, psychical activity, etc and then we have to go back and do all this market research and artificially recreate what was holistic about the more rural way of life.

There really is no free lunch!

deleting fb and instagram, essentially when I was a teenager (which I saw early on was contributing to my depression) was best decision I every made. I moved to a small town from the big city and learned to socialize with people. Coming back old friends comment of how outgoing and easy it is for me to connect with people.

this is true, so we just lack the incentives to make them? a human copilot is just a core part of the sport?

trainsarebetter — Mon, 28 Jul 2025 23:30:57 +0000

This is I’d say partially because we don’t have a HUD that can handle the bandwidth and pace of data required for rally. Overlaying a visualization of the turns ahead would be much better than a copilot for sure

This is pretty naive take. We have turned eras of lush forests into essentially deserts and killed water sheds. These things don’t default back to a thriving ecosystem. Lots of the time they are just dead. Pre tree planting, after clear cutting, there’s a lot of “forests” in bc that are just one canopy hemlock swaths. They need to be thinned and diversified because the are essentially “dead” forests. A lot of work needs to be put into these areas, as the water sheds are falling apart and dying as a result.

Good design is good design. Road dosnt need to be anything more than a path with consistent surface texture.

If we want to develop general purpose machines, then we can rely on placing external sensors in the environment

It’s not binary. You ran way too far. having simple, generalized infrastructure that’s repair ability can be democratized, and having a free market of what can use said infrastructure is robust. Road infrastructure cost a lot of money to maintain, adding more technology to maintain makes no sense

Nonono. Externalizing the part of the compute is bad idea. increasing the cost and complexity of a socialized infrastructure is bad as now it relies on external reliability, we can barely maintain roads in there current form

That’s a good point. I coming from the perspective that waymo is more of a “dead reckoning” approach compared to Tesla long(and maybe never ending) road.

The psychological distinction is definitely something that was perhaps overlooked. we need to put the blame on some one, for closer. Loosing to some rounding error definitely is haunting

Short term, perhaps, long term they might end up with a more generalized robot operating system. It’s definitely more flexible

Sounds like there’s actually around 32ish, based on photos from the “war room” where all the engineers have live feed from all the cars and 112 rides ? https://x.com/aelluswamy/status/1936865682810946035
