The more pressing issue is the fact that critical tools that we depend upon are not properly funded or the incentive to properly maintain them is simply not there. Many of these projects were started as pet projects in peoples spare time. Sure, Google gives a lot of money and contributes to some of these projects but their contributions do not match how much they depend upon them. This is all compounded by the fact that Google is actively working to undermine many of these same projects because they can't get a license change or projects don't want to bend to their will.

Rewriting the world in Rust or other "memory safe" languages is not going to be the silver bullet that is being claimed. In the case of Rust, I am tired of people evangelizing it when it's plagued with issues that undermine its goals and rewrites will bring about more nasty bugs. "Unsafe" code will still need to be written and not being able to use or have stable toolchains to work with is a non-starter for a lot of projects. Until all of these languages have set standards and stable toolchains, hopefully the Rust Foundation will push, these languages are a non-starter.
