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…

Things like: - std::string_view - std::span - std::unique_ptr - std::shared_ptr - std::weak_ptr (non owning reference to shared_ptr, knows when the parent is free'd) - ranges - move semantics - move capture in lambdas - std::variant - std::optional To be honest, learning rust has made me a better c++ programmer as well. Having to really think about lifetimes and ownership from an API perspective has been really neat.…

What are you adding to the discussion? This is a technical forum, the least you could do is comment on the use of Web Assembly in Ethereum or maybe anything of substance. There's a bunch of technically interesting topics to bring up but somehow I doubt you know anything about them.

I speak up against cryptocurrency because it's a cancer. It's a hype adding to climate change without any real world use case whatsoever.

string_view, span and ranges are not conductive to safety, quite the opposite.

Humans are underrated.

You are right, for example, humans don't need anywhere near the amount of training data that AIs need.
