What you call "baffling", I call "different". Being different doesn't mean it's "complex" or even "hard" (in isolation), but it can be baffling, in the same way that driving on the other sid

Equating having access to public transport with lack of running water is wild to me. A rich country is not one where poor people drive but rather one where rich people take public transport.

In order to have true ergonomic no_panic code in Rust you'd need to be able to have parametricity on the panic behavior: have a single Box::new that can be context determined to be panicky or Result based. It has to be context determin

IMO the best chance Java has to close the gap on memory utilisation is Project Valhalla[1] which brings value types to the JVM, but the specifics will matter. If it requires backwards incompatible opt-in ceremony, the adoption in the Java e

It's not "just pointers", because they can have additional semantics and assurances beyond "give me the bits at this address". The index value can be tied to a specific container (using new types for indexing so tha

There's a school of thought that correctly states that in that case it is very easy to cause expensive drop behavior to be ran for each element in the vector where a faster batch approach could instead be done, which is doable if not e

But it makes it free to use public transport on top of that: it encourages people to use it for more than commutes (improving traffic in turn), which makes sense because commutes are peak utilisation time, the rolling stock is under utilize

I explicitly call out how the reduced traffic benefits tradespeople driving their van: every minute they are not stuck in gridlock is a minute they can either bill for or a minute they can get home earlier. We're talking about the pric

It can provide the first 3 of those. And conflating "privacy" with "not being around people" is IMO inaccurate. Not learning how to be around people is also I think a driver of some larger societal issues.
