Highlights from the Existential Hope track at @foresightinst's Vision Weekend UK:

Anders Sandberg (@anderssandberg): Building a Dyson sphere by 2027 might sound like a crazy Twitter idea, until you do the math and figure out how to achieve something like that.

Leah Morris: How we can bridge the gap between the discovery and the real-world impact of a new technology by building infrastructure that helps scale progress.

Christine Peterson (@lifeext): 40 years ago, we had no internet; today we have deep learning; 40 years from now, we might have artificial superintelligence and whole-brain emulations.

Zoe Brammer and Ankur Vora: Predicting the future of AI is hard, but they polled us on when we think we'll have a conscious AI companion and an international treaty on AI.

Jonah Weinbaum (@WeinbaumJonah): A roadmap for building the future we want: find new ideas, research how to prioritize them, head hunt for talent to work on them, and connect talent to funders.
