Plenty of SF is bikeable, but to say hills are a non-issue citywide is ridiculous.
Name a freaking company who's office is in ANY of those locations who's employee population we are talking about.
What's ridiculous is you sound like a person who thinks their millenial perspective is the only thing that matters.
Let me leave you with a litteral quote from my interview at twitter in 2008:
" So tell me how you will do things differently because most people I interview came from facebook as their first job out of college and think that their way is the only way to do anything"
Yeah - you sound like those people. Moronic to think that we are worried about "commuting to russian hill" jeasus.
