(38,302 posts)He pretty much personifies the lucrative (for him anyways...) kind of false optimism that will destroy what's left of the natural world as we know it. I'm pretty sure he's an apartheid asshole as well.
If we believe wind turbines and solar panels and batteries and electric cars are going to "save the world," we are only deluding ourselves. These will only prolong our dependence on fossil fuels, especially natural gas. In fact, an expansion of these technologies to more humans will only increase the environmental footprint of humanity at large.
Seeing wind turbines on hillsides or at sea, and acres of solar panels growing like cancers on previously undeveloped land, does not give me the warm fuzzies. And there's no way in hell this planet can sustainably support an automobile for every adult human, whether it's electric or not.
Human space exploration does not make me optimistic. I'm fairly certain natural humans won't ever have a significant presence in space beyond low earth orbit. We're just too damned fragile. There have been spectacular advances in computers and robotics since we last sent men to the moon so there's no good reason to send human explorers out into space any more -- it's a waste of resources and humans will only get in the way of actual science.
Robotics make me optimistic.
If we natural humans don't destroy our twenty first world civilization, then it will be our intellectual offspring who colonize this solar system; engineered beings who can safely walk naked on the surface of Mars, or fix a problem on the exterior of a spaceship wearing minimal protective clothing... like putting on a coat before going out into frosty weather, no space suit required. Breathing? What's that?
There are things that make me optimistic. The political and economic empowerment of women, easy access to birth control, and realistic sex education will halt human population growth in its tracks. That's a demonstrated fact.
It delights me every time I hear in ordinary conversation a woman talking about her wife, or a man about his husband.
Durable plastic pipe and sophisticated water treatment systems could bring clean water and indoor plumbing to everyone on earth. Modern treatment plants can turn sewage into irrigation water, or even back into tap water. The sewage that goes down the drain in my house irrigates crops, and some of it gets turned back into tap water. I don't have to feel guilty about my flush toilet. My shits not getting dumped directly into some river or contaminating the groundwater my neighbor drinks.
Vegan and vegetarian diets are becoming increasingly sophisticated, both in their own right and with the greater availability of products that mimic meat and dairy products. It won't be long now before the most popular and least expensive burger in your favorite fast food place is vegan, the same as the milk you pour on your breakfast cereal. Unless you want to pay extra for the "real thing" which, hopefully, won't be some animal tortured in a factory farm and processed by abused workers.
I think everyone in the world deserves a reliable, affordable, supply of electricity. The way to accomplish that is with nuclear power, which is an established seventy year old technology far less dangerous, kilowatt hour for kilowatt hour, than any fossil fuel. Unlike complicated "renewable" energy schemes, the components of a modern electrical grid are mostly made of iron, aluminum and concrete. These materials last a long time and iron and aluminum are easily recycled when they are no longer serviceable, in a way that the components of various "renewable energy" schemes are not, everything from wind turbine blades, electronic waste, and lithium batteries.
I think small modular nuclear reactors built in factories and shipped to places that need electric power have a very promising future. I like living in a nation that never abandoned this line of research so we won't be dependent on Russia or China for this technology when it becomes clear to the majority of us here in the U.S.A. that the fossil fuel industry must be shut down.
There's no point to being an "optimist" or a "pessimist" if you don't have any clear vision of a viable and sustainable future.
Personally, I seek to crush the optimism of anti-intellectual intolerant religions, climate change deniers, racists, homophobes, libertarian twits, etc.
