Programming: Current capabilities

Rust’s ownership rules check how memory is used at compile time. This provides a practical alternative to purely manual memory management. It does not prove business logic correct, and engineers still need to understand the boundaries of unsafe code and external components.

WebAssembly gives toolchains a common execution target. That makes portability a concrete capability rather than a requirement to use one source language. It does not automatically provide every operating-system API, remove integration work or make an application secure regardless of its design.
