I live in San Mateo and also pay $50/month for 100mpbs, which is mostly reliable, and the speed is 'good enough'. I could pay more but the gains in speed aren't worth the extra $$. The building next door to me is wired for fiber through one provider, Wave, and offers 1gig for $80/month: https://gowaveg.com https://gowaveg.com. I'd love to switch and pay the extra $30 for much better internet but I can't get access to it as a single customer since it is decided building by building.
