That was just an improvement of the same technology, not an abandonment of the entire technology!

Some day, we might all realize that the digital technology as we know know it is obsolet also but, it may be too late to save the world's knowledge as most digital info is susceptible to radiation.....both man made and natural.

BTW, it is not a widely known fact but, some Russian fighter jets still use some vacuum tubes in their critical circuits because if there ever was a nuclear war, solid state circuits could be wiped out and cripple certain functions of the the aircraft.
Yes, Russia, (along with Chiana) still manufacture vacuum tubes and are considered very high qualty!

Most high qualty guitar amps still use vacuum tubes!
