Imagine: April 1917. A Finnish railway station, a tank, the famous speech "There is such a party!" But Vladimir Ilyich does not deliver it aloud — he writes a post in a Telegram channel. Thousands of workers and soldiers like it, repost "The April Theses" in the "Windows of ROSTA" public group, and Mensheviks try to ban him for misinformation. Sounds like madness, but let's imagine: what if Lenin had modern internet in 1917? Mobile phones, social networks, viral videos, and recommendation algorithms — how would they have changed the course of the revolution, the Civil War, and possibly the whole 20th century?
