40 years ago, you could know one or several microcomputers well, from BASIC down to assembly. But there was even at that time CAD happening on Unix, VAxes driving CAM, the entire IBM universe (from punched cards to RDBMS), and numerical codes like NASTRAN and LINPACK. Generalists are more valuable than specialists. But generalists are doomed to never knowing everything, and knowing what they don't know.
