In case you are looking for the essay on the = sign, this is what Google Bard said:

The reference to the essay by Andrey Kolmogorov in the paragraph you provided is:

Kolmogorov, A. N. (1930). О понятии числа [On the concept of number]. Matematicheskiy sbornik, 38(3), 3-19.

This essay is in Russian, but an English translation is available in the book "Selected works of A. N. Kolmogorov, Volume I: Mathematics and mechanics" (1991).

Do you think it's true? I got my hands on the pdf see no trace of it in table of contents or text searches.

A good question. I've found Bard to be quite good at this type of question in the past but maybe it has hallucinated the answer!

Could it be the author isn't Kolmogorov, but Kronecker?

ChatGPT thinks it might be Paul Lockhart's essay, titled "A Mathematician's Lament".
