Very interesting, however author, probably because of his age, told you bullshit about computers industry in Poland during communism era. Poland has flourishing, internal, computer industry, and I would say, vwry6food one, even comparing to western standards. Models such as Odra ( https://en.m.wikipedia.org/wiki/Odra_(computer) ) was not worse than IBM products, and constrictors designed, at 70ties, several prototypes which fits suitcase and able to be transported by single person. It was groundbreaking conception predating any PC or laptop idea on the western market.
It all ends with 1980, the rise of Jaruzelski junta and War State declaration.
