Self-driving cars. Now that the hype is over and the fake-it-til-you-make-it crowd has tanked, there's progress. Slowly, the LIDARs get cheaper, the radars get more resolution, and the software improves. UE5's rendering approach. They finally figured out how to use the GPU to do level of detail. Games can now climb out of the Uncanny Valley. The Playstation 5. 8 CPUs at 3.2GHz each, 24GB of RAM, 14 teraflops of GPU,…

> The Playstation 5. 8 CPUs at 3.2GHz each, 24GB of RAM, 14 teraflops of GPU, and a big solid state disk. That's a lot of compute engine for $400. Somebody will probably make supercomputers out of rooms full of those. Mmm, this sounds like exactly what people said at the time the PS3 was going to be released, and I can only recall of one example where the PS3 was ever used in a cluster and that probably was not that…

I am also very interested in using worker + kv. Can kv be used as a proper application database? Has anyone ever done that?

If by application database you mean to the level of an RDBMS then no. It's a key-value data store. You get your CRUD operations, expiry, key listing and the ability to do pagination with keys always returning in lexicographically sorted order. Any relation data you want to have would be using the key prefixes, e.g.: article:1 -> {"user": 1, "content": "..."} user:1 -> {"name": "username"} user:1:articles -> [1, ...]

This exactly. The PS5 and Xbox One X are commodity PC hardware, optimized for gaming, packaged with a curated App Store. Sony also won’t just sell you hundreds or thousands of them for some kind of groundbreakingly cheap cluster. They will say no, unless you’re GameStop or Walmart. Everyone with a high-mid-range PC already has more horsepower than a PS5 and it’s not doing anything particularly innovative or groundbre…

I think you've vastly understating current hardware prices. An 8 core 2nd generation Zen chip appears to retail for $290. The PS5 reportedly has a custom GPU design, but for comparison a Radeon 5000 series card with equivalent CU count (36) currently retails for $270 minimum. Also, that GPU only has 6GB GDDR6 (other variants have 8GB) but the PS5 is supposed to have 16GB. And we still haven't gotten to the SSD, PSU,…

Opportunity to give people leukemia. These ideas are at a prehistoric level of biology. We're way beyond this silliness now.

I am talking about work being done in clinical trials at reputable medical clinics. They may be mistaken but I don't think it's "silliness." Here is a recent clinical trial evaluating UVBI https://www.tandfonline.com/doi/full/10.1080/2331205X.2019.1... Of course there are many other mainstream treatments that came from somewhat oddball ideas: Sister Kenney's treatments for polio, the Nobel prize winning discovery by…
