I don't think salaries that high are the norm even in Silicon Valley, unless you're counting "someone was hired with X shares in the company vesting over 4 years as part of their comp package" when those shares were worth $120,000 over 4 years when they were hired but are now worth $800,000. Which, while nice, is more a case of "stocks go up sometimes" than "companies are intentionally paying enormous salaries for people without exceptional skills." Though I'm not actually in SV, and the last time I went on an interview circuit up there was 2015, so it's possible salaries have gone crazy since then.
