Well...those things are verrrrry expensive, it wouldn't be surprising that the owners of those studios will want to maximize the life of those.
But IMHO lang naman, they're on the way out, and analog tape will be used in a different mode (as pointed by abyssinianson)...putting the tracks to analog but further mixing will be done on the DAW, so as to still capture the analog warmth.
Analog mixing engineers will be (if not yet) a dying breed, like programmers of COBOL, or animators who still use a pencil.
Tubes nga din e, dapat obsolete na sya, but they found an irreplaceable home in audio and broadcast applications.
IMHO, school time is very precious, specially these days in schools with 15-week semesters. It could be nice to have a curriculum that's more "forward-looking" so as not to produce graduates who are unusable. Siguro a session or two of analog, para alam nila how it works and for appreciation lang ba. But an entire course for it, for me lang, is superflous. Elective siguro at most, kung talagang mapilit ang estudyante, or they can go and apprentice with our legendary analog engineers after school.
Parang ako nung pagka-graduate ko...I was so brimming with pride. I was armed with the knowledge to design and implement a 600-channel analog microwave system. Pagdating ko sa workplace...ngek...the world has gone digital and I was absolutely clueless about the Digital Microwave Hierarchy.
