Of course. You don't go out naked in winter and dress after you freeze. You
dress first. You have a direct experience to base you actions or. But with
computers it is all based on recommendations (unless you write the program,
in which case you create the update yourself).
Vaccines have harmful effects BTW. A vaccine is practically a disease which
you deliberately expose your body to, so that you force it to increase its
immune protection. If we disregard the torture you are putting the body to,
that may be practical but the fact is - vaccines are mixed with chemicals
which are a form of poison to the body. It needs many years to clean from
those.
Software updates can also be harmful.
The point is... in fields where expertise is needed we replace it with trust
(where we started).
