A non-deterministic compiler would be pretty terrifying. In that case I would expect many people still writing assembly by hand for any serious work. Yes, there is missing/unclear language specifications and compiler bugs and sometimes you get surprised by certain optimizations but you can reason about compilers well enough for practical purposes. Plus it's not economically viable anymore to do without them, sadly.
