So, this is what he told me: unless I'm going to be flying 3 times/week
at least, getting my instrument ticket is a waste and possibly dangerous
as well. He thinks I'll be more likely to end up dead with it than
without it.

This kind of BS just plain ****es me off. You do not become more likely to
kill yourself with an instrument rating and not flying 3 times a week. This
statement is a perfect example of why hours do not necessarily mean
competence in aviation.
