Neither is democracy any more stable. Most democracies before the US (and some after) did not last long due to the difficulties of starting one. After the US got itself established, democracies had more of a fighting chance because the US generally supports them. Communism never really had a country where it went into a stable state (the revolutions which led up to establishing them did not help) so there was no role model or guiding hand to keep them from becoming totalitarian states.
However, Democracy/Capitalism have the same problems as Communism when it comes to long term success. After a while, people in democracy realize that by voting for people, they can get more money. At this point, they do not vote based on the competence or political views (unrelated to money) of the candidate, but on how much money the candidate pledges to give to them. In a similar way, people in communist states (to each according to his needs) realize that no matter how much they work, they will still receive the same amount of money. Even in socialist states (to each according to his contribution), people realize that, much like in democracies, they can influence the amount of money they receive. Either way, the government will slowly devolve into a totalitarian state.
I am not denouncing either of these ideas, though. They are the best methods by which we have come up with for governing, and may be the best we will ever think of. The United States has done very well over its 200+ year course. Nothing can really be said about communism, since at this point it is still waiting to be actually put into practice and not be used as just a slogan. Unfortunately, the US is already showing signs of decline: the national debt is growing as politicians try to bribe voters with even more money while corporations and banks gain even more power (Oligarchy, anyone?). All this will be solved when we get some angels to govern us, but until then, this is the best we've got.
Every current and former Microsoft employee I interviewed, every one, cited stack ranking as the most destructive process inside of Microsoft
... If you were on a team of 10 people, you walked in the first day knowing that, no matter how good everyone was, two people were going to get a great review, seven were going to get mediocre reviews, and one was going to get a terrible review source
This caused projects at Microsoft to stagnate as they became entwined into an increasingly large bureaucracy that prevented actual work from happening. Projects like Windows Reader (Originally an eBook), Vista, and Zune, where Microsoft had several years on their competition ended up being released years later, stripped of features and far from their original purpose. There is no reason that win9 will be any different from win8.
I believe that in the next 5 years, users will be increasingly motivated to change OSs as Microsoft takes yet another plunge in their profits. There are currently 2 other viable options to windows: OS X and Linux (I refer to the FOSS BSDs in this statement as well, though they are not strictly linux). Although OS X has a large fanboy userbase, I do not see it gaining more than 5-10% over the next 5 years, as its overpriced hardware is not comparable to the many cheaper PC manufacturers' products. However, Linux has the power to take the computer world by the storm in the next 5 years, as its many variations form themselves against a unique subset of the computing world.
Linux has a large commercial userbase already, as many companies have searched for a more economically viable solution to windows in the post-recession world. According to two surveys by W3Tech and Security Space released in August 2011 and 2009, respectively, Linux now runs 63.9% or greater of all servers. According to a 2012 survey of companies with $500 million or more in revenues, almost 80% of them foresee an increase in linux usage in their company in the next 12 months, and 71.8% are planning to add more linux computers in order to support "Big Data."
The big obstacle we now face is widespread desktop adoption of linux. However, this may have already begun. Current articles place linux usage from 8-10% and growing (source source). With the failure of win8 eminent, we may finally see Linus's World Domination Plan put into effect."
The trouble with being punctual is that people think you have nothing more important to do.
