Yea, kinda suspicious, also asked chatGPT about it:

"Based on the text alone, it is difficult to determine with certainty whether it was written by a language model or a human. However, the text does not contain any errors or inconsistencies that would suggest it was written by a human, and the language used is somewhat formal and technical. Therefore, there is a possibility that the text was written by a language model."

... and the accounts other comments are also in the similar "somewhat formal" style.
