Was there a time in the past you would have preferred? I grew up in the 90s and I really miss that time period but I don’t think I’d prefer to live at any time before the 20th century over now. As complex and difficult as life is right now, other time periods tended to be much nastier for various reasons.
I admire your optimism! I could easily see us living in a Mad Max situation in 200 years.
One thing I never see people talking about with fossil fuels is that they were a one shot deal in earth’s history, never to be repeated. If global civilization completely collapses (particularly the industrial base) then attempting to start over without fossil fuels could leave us stuck in a 17th century type situation for an extremely long time.
The problem is that renewables just don’t bootstrap. They require huge amounts of minerals which we’ve only been able to mine and process using heavy equipment and manufacturing powered by fossil fuels. Trying to do all that from a minecart-horse-and-pickaxe level of technology isn’t going to work out.
The other major factor is of course all the really easy mineral sources are gone too. Instead of mining directly from the ground we’d be salvaging scrap materials from the mountains of disposable electronics we’re producing right now. That’s where things really start to look like Mad Max.
