I read it and was disappointed, it's okay but probably my expectations were too high for this classic.
I would recommend Snow Crash instead, another Sci-Fi classic from the same era which I found to be a much more enjoyable read & more commensurate to the hype.
Wasn't there a better technical way to block the scraper? Like blocking IPs/domains at ingress instead of serving requests? Probably you do still pay for request traffic though...
Isn't there a market for anti-DDOS third-party services for API endpoints (Cloudflare etc) — through probably for "Free Speech Extremist" that wouldn't be suitable solution, and there are charges too (though presumably when facing a situation like this you actually save money).
Am I the only one wishing I could see the original afterwards, for comparison?
So, a hackier version of Tesla's autopilot? Sounds, uh, terrifying.
I think it did much better on safety in some tests (no I don't have sources, going from memory :/), but is less capable by design on some more trickier scenarios. Basically pretty much what you would something like this to be.

Our best estimate for how much faster the Go code is (in this situation) than the equivalent TS is ~3.5x
In a situation like a game engine I think 1.5x is reasonable, but TS has a huge amount of polymorphic data reading that defeats a lot of the optimizations in JS engines that get you to monomorphic property access speeds. If JS engines were better at monomorphizing access to common subtypes across different map shapes maybe it'd be closer, but no engine has implemented that or seems to have much appetite for doing so.
I used to work on compilers & JITs, and 100% this — polymorphic calls is the killer of JIT performance, which is why something native is preferable to something that JIT compiles.
Also for command-line tools, the JIT warmup time can be pretty significant, adding a lot to overall command-to-result latency (and in some cases even wiping out the JIT performance entirely!)

geohot is a deeply unserious person.
(See also: his attempt at self-driving, and his "internship" at x/twitter under Elon)
His "attempt" at self-driving is better than most of the industry, at a fraction of the cost.
The man does and tries things. Man in the arena.
You also don’t have to start with a program that invokes 20 concepts at once, every one of those rust concepts can have its own hello world, introducing one concept at a time. Frankly several of them are just fundamental CS concepts.
