GP is likely referring to the use of electron tubes [1] perhaps juxtaposing (hypothetical Taiwanese) tubes in 1958 with TSMC today(?). A decade earlier, however, the transistor was invented and would replace the use of tubes, at least for computers.

Tubes, aka valves, are still popular in professional and consumer audio equipment, vintage and contemporary microphones, amplifiers and compressors.
