What will the world be like in 100 years?

If we can survive without a massive ecological disaster, either natural or man-made, I foresee a world with far less poverty and bloodshed.

Mankind should progress toward globalization with harmony replacing much of the prejudice, discord and political upheaval, as I feel we are maturing as a species.

Technical advances seem to be increasing exponentially - the world may figure out how best to harness solar power, leading to unlimited energy and advancements in quantum physics might lead to incredible resources, including, just possible, faster than light travel.

I don't think that there will be a greenhouse disaster in under 90 years, though in the future for sure if we keep going the way we are going. Some entire islands have had to be evacuated due to rising sea levels, 'environmental refugees'.

Not sure when, but in the future there will probably be wealthy corporations (such as apple etc) making trade decisions instead of governments, and will influence them to such an extent that they may as well be in charge of world affairs.

Hopefully there will be less poverty, but by 2100 I believe there will still be a long way to go.

I am optimistic about the future though! people will learn from our mistakes, as we have learned from others. As the species evolves, I think society will evolve in ideas and compassion.

Do you mean 2116?

2100 is only 84 years away - that's nearly 20% less time than you were asking about.
