It would take a long time to answer this in full, and not everybody would agree about what is an advantage or disadvantage. Still, there are probably some advantages everybody should agree about. These include:
Advances in medicine, increased lifespan in many countries, much better communications (look how we're communicating at this moment!) easier travel, the spread of knowledge by means of the internet etc. In many countries we can add the spread of democracy, the spread of women's rights and advances in science of all kinds.
Most people would agree on certain disadvantages too:
overcrowding, pollution, resources getting fewer and being fought over., with inequality growing all the time. Many of the advantages I mentioned above contain disadvantages within themselves. For instance, better technology also means more powerful weapons. Better communication means that rumours, conspiracies and hatred can be spread more quickly. Longer life often means longer illnesses... and so on.
One thing you can say for sure - it was an exciting time to be alive (in both a good and a bad sense) and the 21st century will probably be even more so.
