Why is the Rust compiler so slow?

That person seems to be confused. Installing a single, statically linked binary is clearly simpler than managing a container?!

From the article, the goal was not to simplify, but rather to modernize:

Containers offer many benefits. To name some: process isolation, increased security, standardized logging and mature horizontal scalability.
