You can't make a single typo in Bash and also the browser makes aliases for you automatically based on usage, whereas Bash aliases require thought and maintenance.

So it's Bash that is slower ("heavyweight") if you count how many neuron firings it takes and how much these gigantic, slow write heads (fingers on a keyboard) have to move through space as part of the system. Computer scientists haven't been able to make a language with any sort of error recovery because "it would be non-deterministic" but Google (guided by capitalism) was able to see that's what people need. Google search is a programming language/shell.
