There are hundreds of billions of lines of code of critical software[1] written in unsafe languages, that is not going to be rewritten any time soon. Adding memory safety "for free" to such software is a net positive. Current CPUs are limited by power, transistors are essentially free. [1] often the VMs of safer higher level languages, in fact.
