@metin A slightly off-topic but similar anecdote: A Raspberry Pi is about 4.5 times faster than a Cray 1 supercomputer, the fastest computer in the 1970s. It cost about 7 million USD in 1978, which is the equivalent of over 30 million Euros today!
Fun fact: The @Uni_Stuttgart had one of the few back then and still has it on display at the HLRS (one of the best high performance computing centres in Europe).
