And the current optimizing compilers generate surprisingly good optimized code.  Much better than most human produced "assembler" code.  There are still cases for assember code, but it is by far the exception than the rule, normally when specific architechural instructions are needed.

If you have never seen Matt Godbolt's "Compiler Explorer" at https://godbolt.org/, it's worth a look, if comilers are of any interest to you.  For more info, google "compiler explorer".  Also, several podcast with info about it; google 
compiler explorer site:https://embedded.fm/
for more info about the podcasts.
