I'd like to say no, but....
Yeah. Looking at things historically, Democracies tend to fare rather poorly. Either people vote for something stupid that brings about their downfall, some particular voting block gains too much power, and basically uses it to turn the whole system into a self-serving tool aimed at forwarding their own interests and oppressing all others, or corruption and the accumulation of power in certain hands basically turns the whole thing into a de facto oligarchy.
I really don't see our own society bucking this trend. If anything, we're proving the rule.
The only major upside to Democracy is that feeling like they have a say tends to keeps people happy, and therefore minimizes conflict and frees up resources - that more authoritarian governments typically have to devote to keeping people in line - towards other, more productive, uses. However, if civil society breaks down due out of control factionalism, demographic rivalry, or irreconcilable ideological differences, that benefit kind of goes right out the window.
More indirect Republican systems of government were meant to keep such problems in check, by redirecting public sentiment towards productive ends, and limiting the amount of damage populist direct democracy can do. Unfortunately though, democratic pressure tends to slowly but surely erode such counter-measures over time, making the issues mentioned above more or less inevitable in the long run.
