Capital and maintenance costs were big hurdles, not to mention the additional cost of improving the manufacturing equipment and machines (remember Moore’s Law).

These issues were resolved with innovations in EDA and the publication of “Introduction to VLSI Systems” (that lead to the creation of simplified abstractions to manage chip design complexity), aaaand… the fabless fad was on.
