This is a textbook example of survivorship bias.
Survivorship bias, or survival bias, is the logical error of
concentrating on the people or things that "survived" some
process and inadvertently overlooking those that did not
because of their lack of visibility...A commonly held
opinion in many populations is that machinery, equipment,
and goods manufactured in previous generations often is
better built and lasts longer than similar contemporary
items...Again, because of the selective pressures of time
and use, it is inevitable that only those items which were
built to last will have survived into the present day.
Therefore, most of the old machinery still seen functioning
well in the present day must necessarily have been built to
a standard of quality necessary to survive.
