  • You can’t use phone calls or texting when your family lives in the other side of the globe. Many parents are not tech savvy for them to be able to use something else if you aren’t there to set it up. Lot’s of them got into Facebook, and their friends are there, and we need to be there for them to reach us. It’s the network effect.

    Also for many parents, internet = Facebook. They don’t even use emails, or any other services for that matter, maybe news websites that are bookmarked in their browser years ago by their children.




  • As others have mentioned they already do that to a degree they can with the uncertainty of forcast. It’s called Forcast Informed Reservoir Operation (FIRO).

    Important thing is that the forecast is uncertain farther you go in future, and smaller the area you’re looking at. So the policies will have to take that into account, you can’t simply empty your reservoir because if your forcast is wrong and you don’t get enough rain, then you don’t have the precious water anymore for dry season. But if you’re wrong on the other side you get flood issue.

    Satellite data and a lot of ground sensors are in place that help us better forcast the future storms along with improved computation and technology, but nothing is sure, and it might get worse with current situation. We already have problems because of previous funding cuts causing us to lose so many sensors.

    Also a fun fact, we’ve had dams for so long that we don’t know the natural flows for so many rivers so we can’t calibrate our models well. Basically we built dams long before we started measuring the rivers. I’ve been meaning to publish this, but it’s just stuck in a draft for almost a year now :(
















  • Same way people in the past probably said there’s no way you can make anything work without a mechanical mechanism? Can you imagine what an electronic device/chip would look to someone from far past? People thought humans couldn’t fly.

    Those “fundamental science” is just us making sense of the universe in a way we can observe it and even then we don’t know everything. Can you imagine how different the universe looks if you just shift the electro magnetic waves you can see.
