Stumbled upon my grandpa's avionics toolkit and it's splitting our shop views

I was cleaning the storage area last Friday and dug up his old tool roll from the 70s. It's full of analog meters and hand tools we barely use now. Today, we mostly rely on digital test sets that give us readouts in seconds. Half the crew says working with physical gear taught them to really understand the systems. The other half loves how new tech cuts down on guesswork and keeps flights on time. I've seen both sides, like when a digital diagnostic missed a corroded connector that a simple continuity test found. What do you all think? Are we losing something important or just getting better at the job?
