To be fair, the comparison is a bit ridiculous. A modern mobile phone is an ultra compact, very powerful computer primarily with a data connection that is faster than many large cities had in their entirety in the 1970, and it only incidentally makes phone calls.
I can’t even find an analogy that fits. A wash board has more in common with a brand new digital front loader washing machine than a smart phone has with a rotary dial phone and a steam engine certainly has more in common with a 2021 hybrid car.
If there’s one set of technologies that’s changed beyond all recognition it’s telecommunications.
Actually some of the concepts in microchips would have more in common with some of the concepts found in crossbar switching matrixes and their registers, but only at the most macro level.
So you could say a smartphone has more in common with a Western Electric No 5 crossbar or an Ericsson ARF than it does with a dial phone.
Also some of the software run on smartphones, including Unix has its origins in early digital switching systems and many computer and digital transmission technologies come from telecommunications research in the 50s-70s.
So you’d recognise more of the echos of old phone network equipment in the hardware of your smartphone than you would find anything in common with an old rotary dial PSTN telephone itself.
