Nope, you're totally wrong. It's that pesky human temporal bias.
Shits gonna change, yo!
I mean, I know you don't think about it much, even the humans that do, well... their speculation is usually 38 shades of WRONG!
I mean, you look at depiction of the "future" from the past and... wow... yeah, really not so much with the accuracy.
Shits gonna change tho. It always is.
I mean, take global warming for example, it's probably going to take less than ten years for society to figure out that we should start treating our industrialization like a living thing and work on integrating it into our existing carbon cycles.
It will reach a point where it's not about "reducing carbon emissions" but rather "recycling carbon emissions". Basically you harvest the CO2 and then use in algae based biofuel production plants.
Same with so many other things. Take plastic for example, they've recently discovered how to make infinitely recyclable plastics as well as quick biodegradable plastics made out seaweed and such... that you can even eat!
Eventually most of our packaging will all be bio-matter based and, as such, will be easily recyclable into biofuel. I mean, even right now, 80% or our organic waste is going into giant holes in the grounds... which is a giant stupid waste of money since that organic material can be converted into biofuel. Several cities across the globe have already started building biofuel production facilities specifically for that purpose.
As far as germs and viruses and so forth... sorry kiddo, but the future is already here... it's just not evenly distributed...
The newest versions, that use UVC, can even be used directly around humans since they don't cause cancer... although they do rapidly break down certain chemical bonds, so you need to be careful using them around unshielded plastics and rubber.
Every problem you THINK is going to be around in the future... won't be.
But, if it's any consolation to your fear mongering hysteria... there will be lots of NEW problems to deal with in the future. Shit you don't even want to fucking know about!
