This just in: there's bias based on appearance. Outside of SV, being the wrong skin tone, wrong gender, not pretty enough, too pretty, not tall enough, etc are all attributes that have been unfairly affecting workers, since, well, forever.
You would have thought when you're engineer you'd only be judged based on your technical skills, your work output, performance, efficiency, ideas, design etc. Most of my team is remote so for all I know they're just those things I listed above, and a voice and a pixelated set of images Google hangouts show me. It's devastating that people still need to be discriminated in this industry.
If you're a brilliant programmer, but an asshole and proud of it (or unaware of it), then yes, you will not get far on your skills alone.
Whether we like it or not, we are all part of a society, and those who choose to rebel against that, well, that's thier choice and accept the consequences. (Follow up: you can't really hide behind remote work if you lack social skills. Possibly, but not very likely.)
EDIT: Snark removal.
