Found it! It is "...et in pulverem reverteri", a short story by Janusz Zajdel, one of the best polish scifi writers, think Lem/Asimov/K.Dick https://en.wikipedia.org/wiki/Janusz_Zajdel

It was published in a collection https://pl.wikipedia.org/wiki/Ogon_diabła

Google translate: https://translate.google.com/translate?hl=en&sl=pl&u=http://...

Whole collection is high quality scifi, equal to Asimovs 'The Last Question' for example.
