AGI will make the economy far more efficient, increase the rate of scientific innovation, etc. For example, some ancestor of alphafold could spark a revolution in genetic engineering, creating crops which are far more efficient and resilient, etc.
Hoping that someday soon^tm someone will come up with something that makes all the current mess go away is a dangerous path.
In germany they call it 'Technologieoffen' - and even some political parties have written it on their flags. 'No need to implement changes now - someday God will decent and absolve us from all of our sins - until then party hard! #yolo'
I'm all for accelerating research/tech. But it can't be an excuse to just let sh*t happen. Yet most people will do this - it's expected human behavior.
Add to that the amount of junk papers that will be generated and published - through which all future scientists will have to sift - and AI in it's current form is much more likely to be a concrete block dragging scientific progress down.
Expecting it to happen just in time to save us from ourselves? That sounds more like religious belief to me. We're burning down the garden in the hope we will find a yellow brick road under the ashes.
