Myth and religion are the giants that todays science is standing on.
"If I have seen further than others, it is by standing upon the shoulders of giants." -- Newton
Todays universities where born out of the church. I will just gonna quote wikipedia[1] here: "These universities evolved from much older Christian cathedral schools and monastic schools, and it is difficult to define the exact date at which they became true universities, although the lists of studia generalia for higher education in Europe held by the Vatican are a useful guide."
Dismissing our past is certainly not the way to go.
just because something had value before doesnt mean it still does.
Taking your example "8-bit processors": it still has value. Even if it is only for learning purposes.
