The fundamentals of solid state physics haven't changed much in 30 
years....    ;-)

It's a tribute to semiconductor scientists that our fabrication 
processes have been delivering devices with very close to theoretical 
performance for ~50 years.  (But I'm still waiting for commercial 
graphene FETs.)

Best regards,
