i'm not sure why you're mixing and matching stuff about electrical cables causing fires and the San Bruno explosion. upgrades are expensive, PG&E is barely profitable, and it operates in a very challenging regulatory environment. California liability law + juries impose extremely outsized liability judgements compared to the rest of the country... other utilities have caused actions that lead to death but it generally does not mean billions of dollars in liability judgement. Compare the West fertilizer explosion in Texas, the liability it generated, with PG&E liability judgements. I understand that it is always attractive to have a simple explanatory story with a clear villain. I encourage you to resist that appeal.
