For me the video was really interesting.
Few things one might consider:
1. The storm is around 12% likely to happen in the next decade
2. We don't have enough data about the previous one's.
They caused a massive outage all across Canada for around 9 hours, therefore even if it happens this time, there will be a chance of it being affecting things for no more than days.
3. We do have a whole decade to prepare therefore most probably the scientists would be able to tackle this issue, the issue would be with the wires passing through the oceans, so I do think what might solve this is :
**Creating more hubs like Singapore across the equator to make sure things are under control.**
4. It would not affect all the business for sure, the higher chances of it affecting the world trade and the satellites cannot be disregarded, but what matters is making the communication between the countries stronger perse and enhancing the local businesses as well.
-The whole thing would be a nice competition for the scientists to tackle and right now and research needs to be done on this topic more.
