You're talking about modern-day humans like they are the same as our ancestors from 30 000 years ago - I think modern-day humans aren't all that capable without the fancy toys of the last 200 years.
We are mostly the same. We have the advantage of being born as a clean slate, which means that in difficult environments new generations adapt to environment and control it, we live in good times now, but we can still see human engenuity in many ways.
