I'd say he found the right list ;)

Subject: Seeking disruptive tech

I just realized I am the same age as the transistor (though it in fact got smaller as it got older, and I did not).
Does anyone know please of a forum (this one?) with interest in disruptive technology, i.e. components or processes that quickly changed the gameplan?
Obviously at some tipping point ICs became cheaper and easier than analog components, in 1945 V2 weapon guidance has mechanical gyros, but
15 years later a Minuteman uses quad nand gate ICs.
Behind DEC's PDP-1, funky light brown paint and all, is presumably some contemporary innovation in packaging or fab process?  I never had a relationship with a PDP-1, but I could generate similar nostalgia for the first commercial use of VHDL, for instance.
Any idea where people like me go to live again my idea of the good old days?
