By reading the responses one can tell how much ignorance and paranoia there is regarding new technology. Doubt that a single response is accurate or reasonable.

The evidence continues to suggest that computer architecture is moving away from classic Von Neumann to data flow architectures. Part of the magic that will hopefully make the transition work seamlessly is advanced compiler technology.

The real tragedy in the US is that there are 2 political camps that just mock each other. Wolfers knows better. The original post by Wright is technically correct but poorly phrased.
It's really quite a thing to have a Secretary of Energy who does not understand, ummm... energy.

Ford's and Tesla's manufacturing processes, although developed separately, are converging. Key similarities are:
-gigacasting
-structural batteries
-assembly tree(instead of assembly line)
All resulting in lower cost vehicles.

Coverage of protests happening in US are getting wildly suppressed through media & online. If you've heard people talk about the "Music Festivals" this is why.
So please be safe, keep your ear to ground, and support your local music festivals y'all! 🎵✊

The US is run by morons thinking they can get win-lose deals. The US breaks treaties on a whim and then engages in textbook bad faith bargaining. This will result in lose-lose outcomes for everyone. Fortunately Canada still has the rest of the world, who believe in win-win deals, to trade with.
