The internet has made a lot of people armchair experts happy to offer their perspective with a degree of certainty, without doing the work to identify gaps in their knowledge. Often the mark of genuine expertise is knowing the limitations of your knowledge.
This isn’t a social media thing exclusively of course, I’ve met it in the real world too.
When I worked as a repair technician, members of the public would ask me for my diagnosis of faults and then debate them with me.
I’ve dedicated the second half of my life to understanding people and how they work, in this field it’s even worse because everyone has opinions on that topic!
And yet my friend who has a physics PhD doesn’t endure people explaining why his theories about battery tech are incorrect because of an article they read or an anecdote from someone’s past.
So I’m curious, do some fields experience this more than others?
If you have a field of expertise do you find people love to debate you without taking into account the gulf of awareness, skills and knowledge?
I recall hearing about this one informal conference between climate scientists, ethnographers, and collapse-aware economists. About two dozen ppl in total, IIRC.
Their exceedingly conservative estimate of the BAU path had humanity experience a 40-60% collapse (3.2B to 4.8B dead) by some point in the 2050s. And you don’t see that without a whole hell of a lot of secondary civilizational/technological collapse and loss of knowledge.
And they concluded that humanity existing past 2150 or 2200 was vanishingly unlikely due to polar restriction due to lethal wet bulb temperatures making the rest of the planet uninhabitable for year-round occupation, and the sheer lack of arable land in the polar region.
The problem is that we have been accelerating past 1.5℃ of warming in terms of CO2 production. We haven’t even begun to slow down, much less reverse to net zero. And since climate change has an inertia to it that is thousands of times stronger with our current change than in prior changes, there is now a non-zero possibility that - even if we go extinct - the planet itself could end up in a Venus scenario. Things are moving just far too fast for any ecosystem - much less the entire planetary ecosystem - to adapt and migrate in order to remain maximally productive in natural CO2 sequestration.
