My own line of reasoning is that the speed of progress of technological advancement is dependent on the amount of people who can dedicate their lives to doing stuff other than trying to gather enough food and shelter to survive. So for the longest of times basically everyone had to just try to survive and maybe have an idea or two every now and then. Low human population and no-one able to dedicate themselves to innovation means extremely low innovation rate. But those rare times something really useful was developed and passed on to the next generation led to freeing more people to be able to dedicate themselves to innovation and thus increasing the amount of people one human can support with their work effort. This is a positive feedback loop so it has exponentially grown to today where one person's work can support multiple people making theoretically most of humanity free to advance technology.
It's quite obvious it's true when looking at history.
"Idle hands are the devil's playthings" is a really stupid saying, unless one truly does think of the devil as the Lightbringer.
Honestly the more one reads into history, the more one realises just how progress stifling Christianity has been. (Or Abrahamic monotheism in the first place.)
When the people around modern day Greece started having extra fish and wine so some of the ppl could take it easy and just chilax, they basically came up with the central ideas that are still central to our modern society. Democracy, morality, freedom, etc.
