That might have been stated somewhat sarcastically, but then again it might not be too far from the truth. Acoustic instruments clearly predated amplified ones, and amplification was surely born out of an interest to overcome the practical limitations of the purely acoustic ones. Distortion must have been an unintended side effect, that has become for some time a desired one. It didn’t take long in playing live acoustically with a microphone, for even my little brain to observe first hand the challenges of playing acoustic guitar live…What will happen when most people do not have electricity? Acoustic it is. Honestly, there will always be tubes as long as there are other things.
Maybe a good related new development in technology will be (if it isn’t already here)…
Tech or ways to use it, to make amplification that is inexpensive, easy to implement, and realistic sounding and feeling; for acoustic instruments like guitar. Imagine a large audience being able to hear the full beauty of an acoustic guitar, played live - realization of the original goal of amplification, inexpensively and easily.
