> Web development without garbage collector sounds like a bad idea.

Before rust, all the mainstream non-gc'ed languages (i.e C/C++) were not recommended mainly due to potential security issues.

The only options left were gc'ed languages (e.g Python, Java, Go).

Now Rust enters which addresses a lot C/C++ issues but the ergonomics, lack of tooling & learning curve is too much for lot of basic web services.

For large scale web services, investing in Rust makes sense to make it more performant & resource efficient, especially a lot of $$ is riding on it.
