tbh I'm not dyslexic and realized the spaces make it really difficult to know what the filename actually is. If you just take the second example, how would you know if the file was "this is my config.txt" versus "config.txt"?

Aside from parsing errors it just seems to lend itself to ambiguity.

This. People are saying spaces improve ergonomics. Unless everyone always quotes their paths in documentation, emails, etc -- which they won't -- I say it actually reduces readability.

Also programs automatically that turn paths into links don't work with spaces.
