I think so. 40,000 is well back into the stone age, and not even the most recent era of that. So we hadn't formed governments and societies yet, or law, or developed farming and/or animal husbandry to the point of being free to address other things. However - if you would say 3,000 years, then no, not much. Which puts the explosion of technology we are currently seeing more like being inside a slow-motion explosion than progress. It's all happening in an instant, while the child has only advanced about a second in maturity.
