That’s fascinating! What do you think were the key differences between the 2016 approach and the 2018 approach, and how much was just luck of timing?
I think three key differences:
By 2018, we had more of a track record before starting.
For the 2018 attempt, we self-funded for six months before seeking funding to build an even bigger track record, rather than trying to get funding right at the beginning.
EA funding was notably more plentiful in 2018 than 2016. (Though still notably less plentiful than in 2022.)
