People purposefully avoided probabilities in high risk existential situations in the past. There is only one path of events and we need to manage that one.
OTOH, The precautionary principle is too cautious.
There's a lot of reason to think that AGI could be extremely destabilizing, though, aside from the "Skynet takes over" scenarios. We don't know how much cushion there is in the framework of our civilization to absorb the worst kinds of foreseeable shocks.
This doesn't mean it's time to stop progress, but employing a whole lot of mitigation of risk in how we approach it makes sense.
The simplest is pretty easy to articulate and weigh.
If you can make a $5,000 GPU into something that is like an 80IQ human overall, but with savant-like capabilities in accessing math, databases, and the accumulated knowledge of the internet, and that can work 24/7 without distraction... it will straight-out replace the majority of the knowledge workforce within a couple of years.
The dawn of industrialism and later the information age were extremely disruptive, but they were at least limited by our capacity to make machines or programs for specific tasks and took decades to ramp up. An AGI will not be limited by this; ordinary human instructions will suffice. Uptake will be millions of units per year replacing tens of millions of humans. Workers will not be able to adapt.
Further, most written communication will no longer be written by humans; it'll be "code" between AI agents masquerading as human correspondence, etc. The set of profound negative consequences is enormous; relatively cheap AGI is a fast-traveling shock that we've not seen the likes of before.
For instance, I'm a schoolteacher these days. I'm already watching kids becoming completely demoralized about writing; as far as they can tell, ChatGPT does it better than they ever could (this is still false, but a 12 year old can't tell the difference)-- so why bother to learn? If fairly-stupid AI has this effect, what will AGI do?
And this is assuming that the AGI itself stays fairly dumb and doesn't do anything malicious-- deliberately or accidentally. Will bad actors have their capabilities significantly magnified? If it acts with agency against us, that's even worse. If it exponentially grows in capability, what then?
Are children equally demoralized about additions or moving fast than writing? If not, why? Is there a way to counter the demoralization?
Yes, if we're concerned about the potential consequences of releasing AGI, we need to consider the likely outcomes if AGI is released. Ideally we think about this some before AGI shows up in a form that it could be released.

Absent large interventions, this will happen.

Absolutely basic arithmetic, etc, has gotten worse. And emerging things like photomath are fairly corrosive, too.

We're all looking... I make the argument to middle school and high school students that AI is a great piece of leverage for the most skilled workers: they can multiply their effort, if they are a good manager and know what good work product looks like and can fill the gaps; it works somewhat because I'm working with a cohort of students that can believe that they can reach this ("most-skilled") tier of achievement. I also show students what happens when GPT4 tries to "improve" high quality writing.
OTOH, these arguments become much less true if cheap AGI shows up.
