Disagree, having dealt with +40k LoC rust projects, bottow checker is not an issue.

Async is an irritation but not the end of the world ... You can write non asynchronous code I have done it ... Honestly I am coming around on async after years of not liking it... I wish we didn't have function colouring but yeah ... Here we are....

I strongly disagree with this take. The borrow checker, and rust in general, keeps reasoning extremely local. It's one of the languages where I've found that difficulty grows the least with codebase size, not the most.

The borrow checker does make some tasks more complex, without a doubt, because it makes it difficult to express something that might be natural in other languages (things including self referential data structures, for instance). But the extra complexity is generally well scoped to one small component that runs into a constraint, not to the project at large. You work around the constraint locally, and you end up with a public (to the component) API which is as well defined and as clean (and often better defined and cleaner because rust forces you to do so).

This hasn't been my experience at all.

I still regularly use typescript. One problem I run into from time to time is "spooky action at a distance". For example, its quite common to create some object and store references to it in multiple places. After all, the object won't be changed and its often more efficient this way. But later, a design change results in me casually mutating that object, forgetting that its being shared between multiple components. Oops! Now the other part of my code has become invalid in some way. Bugs like this are very annoying to track down.

Its more or less impossible to make this mistake in rust because of how mutability is enforced. The mutability rules are sometimes annoying in the small, but in the large they tend to make your code much easier to reason about.

C has multiple problems like this. I've worked in plenty of codebases which had obscure race conditions due to how we were using threading. Safe rust makes most of these bugs impossible to write in the first place. But the other thing I - and others - run into all the time in C is code that isn't clear about ownership and lifetimes. If your API gives me a reference to some object, how long is that pointer valid for? Even if I now own the object and I'm responsible for freeing it, its common in C for the object to contain pointers to some other data. So my pointer might be invalid if I hold onto it too long. How long is too long? Its almost never properly specified in the documentation. In C, hell is other people's code.

Rust usually avoids all of these problems. If I call a function which returns an object of type T, I can safely assume the object lasts forever. It cannot be mutated by any other code (since its mine). And I'm not going to break anything else if I mutate the object myself. These are really nice properties to have when programming at scale.

async seems sensible for anything subject to internet latency.
