all jobs are based on specialized tasks - and computers surpassed humans in that particular area over 10 years ago).
This is a false correlation. While all jobs are specialized, they are not all repetitive. Computers are good at the latter, not the former. So, yes, many industrial jubs such as manufacturing can be better done by computer/robotics, it will be far into the future before we have robot cops for example.(Robocop jokes aside). I can think of many jobs that won't be replaced anytime soon. I'm not saying there will be enough to employee everyone, but don't pretend there won't be work to be done.
As for replacing the monetary system, even in a world of free consumer goods and abundance there are still things that will have value - without money, how would you decide who gets them? For example - who gets to own all that beach front property? That cabin in the mountains? What is the motivation to create 79 episodes of Star Trek? For the guy that does all the crap things that barely rates a name in the credits?
You haven't thought this "money is going a way soon" bit through very well.
Monetary systems work. Want to do away with it? Come up with a better replacement first. Then have fun trying to get the entire world to agree to it.
