My points it that without humans having developed space technology you would not have GPS or the ability to phone people on other continents or transmit data to them via the internet because this technology relies on satellites which are…. in space.
The fact that you are posting on the internet and presumably use a mobile phone etc shows that you are “interested in it” otherwise why are you doing it?
Also presumably you never want to travel on a plane again, and don’t want the products you buy that are produced in other countries (most of your food, clothes, fuel) anymore as that would not be happening without these modern navigation systems which were developed…. from our exploration of space.
Yes, you would be substantially worse off than before the internet existed, because the global population was lower at that point and global interconnectedness of trade and reliance was far lower, so supply chain disruption that you would experience if these systems ceased to exist now that almost every company on Earth’s supply chain and communications rely on these systems would be more than you seem able to comprehend and you’d quickly find yourself with no power, food, or clean water, no way to contact anybody and roaming hordes of desperate people quite happy to attack you and take whatever you have unless you are physically strong enough/ well armed enough to repel them.
Sounds like a great plan for the summer.
I think I’d rather stick with scientific progress, personally.
