You gotta be f**** kidding me. That a person old enough to know how the computer keyboard works thinks that lack of computers lead to downfall of communism OR might be interested in seeing the USSR of all things back? I honestly can not believe this. I have no faith in humans whatsoever, and it still too much and I outright refuse to believe that. Tell me that some troll hacked your account. Also, actually, you got the automation part pretty much wrong way. In communism, the work is the ultimate good, and everybody should work because work is good. In capitalism, if you can get away with not working (because, for example, your spouse earns enough money), hey, good for you! So yeah, lack of work is problematic with communistic society, but not as much of a problem in capitalism.
Hmm... Somebody poses an interesting hypothetical and you respond with an emotional barrage. A'ight, lets do this.
You seem to not understand how automation affects an economy. You see it makes specific jobs redundant. For example, only 300 years ago about 90% of the workforce was employed in agriculture, but these days that has dropped to less than 2%, without triggering any sort of food shortage. This is because agriculture has taken up automation. Crops are sowed, watered and harvested on mass with great big machines driven by a single person, rather than by hand by a very large workforce. Reducing the labor demand of an industry has allowed people to move into other industries, industries that provide us other cool things like monster trucks and vidya games.
So, automation is the greatest gift to a capitalist society because it allows people to make a greater economic contribution per person and therefor things can only get better, right?
WRONG!1915 was the peak year for the horse population on earth. Since that year their population has rapidly dropped because they have been made redundant and replaced by cars. It isn't that horses are lazy, it is just that they are incapable of preforming as well as a car, and this leaves them with nothing to contribute to the economy. They are pretty much redundant. The free market doesn't just magically make jobs for horses because their old positions were automated, and in economic terms
there is no difference between a human and a horse.
It is easy to assume humans will always be able to fill a role that automation can not, but to do so is stupid. The transport industry is one of the biggest in any developed nation, but it is going to change very quickly within our life times with the introduction of self driving vehicles. There are machines that test the interactions of different drugs at a rate of thousands a day. What once took an entire floor of accountants to do is now done using a few megabytes of software. The vast, vast width of our economy is subject to automation, and humans, like the horse, will become redundant.
We are approaching a thing called 'near zero employment' where a very small fraction of humans are able to do anything of value. So how does a capitalist society function is such a technological environment? Well it just doesn't. When wealth is awarded to work, and nobody can work, things break down. The only possible solution is through wealth redistribution, a concept much more closely linked to communism than capitalism.
Study the intersectionality between macroeconomics and technology and everybody turns post-scarcity socialist sooner or later.
