I think that may be an insight to something quite profound. We used to measure the "doubling of knowledge" against number of peer-reviewed papers of scientific research etc. Now not so much. "Knowledge" has become mor

I agree the administration tariffs "wouldn't be levied on manufacturing inputs" if they really wanted to help domestic industries. I'm not saying they're doing the right thing, I'm just saying that most Americ

Most people here in the US that I talk to understand that the additional tariffs imposed by the Trump administration are an attempt to get domestic US industries to produce the items that are now being imported subject to the tariff. In so

While Walmart has historically denied using "individualized" pricing (charging two people different prices for the exact same item based on their income), they do use behavioral targeting [1] Members of Walmart+ often see differen

Why is knowledge doubling no longer used as a metric to converge on the limit of the singularity? If we go back to Buckminster Fuller identifying the the "Knowledge Doubling Curve", by observing that until 1900, human knowledge d

This makes a lot of sense. The commercial launch business is not large enough to support all possible Falcon launches, so Starlink was created to take advantage of the low launch cost and vertical integration and is now a major profit cent

It is often argued that the US will grow its economy such that the debt is less significant. There is much confusion between the US debt being cited as a ratio of GDP (common among economists) vs net tangible assets (common among businesse

Agreed. However, the 2020 Census had a reported "net coverage error" of only about -0.24%, which I seriously question in the case of SD.

Even in the USA, the census is not as accurate as it thinks (without even getting into the homeless situation). South Dakota is the capital of the "Nomad" phenomenon because of its favorable residency and tax laws for full-time t

Yes current EVs are heavy. It's not at all clear that this will prevail as solid state batteries evolve to become standard. It is highly possible that EVs will soon be lighter than comparable ICE vehicles [1] [1] https://n

The assertion that 'I just hope "dumb" EV's become a thing soon' led me to a different assumption. The ultimate aspiration of a "smart" EV is self-driving, which incorporates Internet connectivity feature

That is not the argument being made. We are discussing how "dumb" vehicles (e.g. vehicles that contribute to 50,000+ fatalities annually) provide independence, privacy and freedom that "smart" vehicles (e.g. vehicles wi

So liberty then. I don't disagree with you, but this modern flashpoint in the classic debate between individual liberty and collective safety does bring up the question what is saving 50,000+ lives annually actually worth in terms of

Why? Are you worried from a liberty/privacy standpoint? "Smart" EV's are demonstrated to be significantly safer than "dumb" EVs. Waymo’s 2025/2026 data shows an 80–90% reduction in injury-causing crashe

I wonder how much the 2026 SNAP food stamp item rule changes will move this needle further, with several states using new federal waivers to restrict "junk food" items like soda, candy, energy drinks, or prepared desserts?
