They had the most efficient census of any European country. So when the Nazis came in and replaced the moderate Democratic Monarchy all they had to do to round up all the Jews was to select the column for religion on the IBM punch cards from the last census.
It's a travesty that next to no one knows the fact that the holocaust was the first large application of computers and the atom bomb was the second.
Almost everyone knows the Nazis used census data to initialize the Holocaust, it's practically the number one argument given against mass surveillance and data collection of any kind, and of censuses in particular.
Also, Allied cryptanalysis of German ciphers (particularly the Enigma code) was, arguably, the second large application of computers, and by the time we got to the atom bomb, I think they had already been in widespread use for radar and missile trajectory calculations.
e.g. This is a fire control mechanism for ships.

Very clever stuff indeed.
This is not a reasonable argument because it can be applied to anything. Telephones enables nazis to communicate better. Guns allowed them to shoot faster. Cars made it so they could round them up even more quickly. Without fuel they wouldn't have had any tanks. The list goes on.
The fact that technology empowers nazis as much as good people is trivial and obvious. As an argument against technology it's useless because by that logic we need to go live in a cave again.
