Us old buggers have had lots of changes. In the 50's it was Verichrome Pan roll film, gone.
Then I did 40-50 years Kodachrome and Plus X, gone.
Still using Tri-X but it is not the same emulsion as it was then.
Moved to Ilford papers, film and chemistry but now Cibachrome/Ilfochrome papers and chemistry gone.
Testing Fuji now but astia gone.
Do about 10% digital these days. Should get a large format camera and start coating my own glass plates, ha!
We will carry on with what is left. E-6 is about dead as well, no more slides.
