Russia in 1917 was about as developed as Germany or Japan in 1850 - or Britain in 1750.
The funny thing is that this fact means the revolution totally contradicted Marxist doctrine, which predicts communism as a natural remedy to the excesses of capitalism. Russia hadn't even entered the captitalist "phase" yet - it was literally the least appropriate country in Europe to stage a communist revolution in.
PS: Of course with automation and computing many of the old assumptions stopped applying but it’s hard to complain when someone only sees 75 - 100 and not 150 years into the future.
Also, Lenin's modification of Marxist theory is somewhat irrelevant, the Marxist foundation was entirely wrong on a number of massive points: one more wasn't going to make a difference.
