I don't know that they are making a comeback as much as there is a cottage industry springing up to meet the small demand. Most folks don't want a home computer they can literally walk around in, or a digital watch in a tandem axle trailer.

Imagine what my computer CPU would look like if it were built with vacuum tubes. It would be bigger than my house.

Ok,you lost me... how is a vac tube immune to EMP? Both the Russians and the U.S. lost transmission cables and equipment in testing... can't see how a tube would be spared. Unless you are talking about spares in a box. I retired from USAF in 94, we didn't have anything on the computer side that still used tubes. We EMP shielded rooms and equipment cabinets... would hate to find out if any of it actually works.

When I worked in SAC bomb-wing command posts... in the 70s, when we had nuke-loaded B52s on Alert... our Survivable Low Frequency Communications System (SLFCS) relied on heavy EMP shielded cabinets, and optical-isolators to protect it from TEMPEST threats. O An EMP event will destroy power generation and transmission lines... Without shielding pretty much anything that will conduct electricity is vulnerable... tube filaments will burn out, even if the plates survive. EMP myths: www.thepreparednesspodcast.com/emp-myths/
