> On the other hand, I'm scared that respectable projects like Qt (~6M lines of C++, man-millenia of work!) will be considered "obsolete" by the coming generation and another cyle of wheel reinvention will begin, tossing away man-centuries worth of polished, working code on the sole ground that it's C++.

I imagine that as soon as Rust hits something like version 1.5, we will start to see semi-automatic converters from C/C++ to Rust, something similar to the C-to-Go effort underway to get to a self-hosted Go compiler.

Qt will probably take 5 years to be ported in a decent way, but I am pretty sure that a sizeable part of that codebase will be translated without too many problems, given its relative clarity.
