I might end up using this thread as a generic dumping ground for predictions of mine, but here are several that I think should be added to the timeline now. Most of them are related to the economy, and the value of various technology sectors.

2026: The Hyperloop is a $6.3 Billion Industry
Probably there will by hyperloops complete or under construction on three continents. Worth noting that.
2035: The Industrial Internet Is Contributing $10-15 Trillion to the Global Economy
2060s: A $1 Quadrillion Global Economy
