A Russian economics expert had been making money through long-short strategies during the Russia-Ukraine war. Despite his economic success, he felt deep regret about Russia's historical mistakes. He wrote on his blog that "Russia has been on the wrong path since the 19th century," critically analyzing Russia's history. Then, remarkably, he traveled back in time to 1891 and found himself in the body of Russian Crown Prince Nicholas II during his visit to Japan.
Though Nikolai's efforts weren't entirely in vain, ultimately there were no "era-transcending new weapons 20 years ahead of technology!"
Because what Nikolai remembered was just the practical aspects of specific weapons - their effectiveness in various scenarios, their tactical applications on the battlefield, and their designated combat roles. He lacked the intricate details of their developmental processes, the complex engineering challenges overcome during their creation, or the countless technological innovations and design iterations that brought them to their final forms.
