Salam aleykum
I dont know what to say but i read in Quran about great generations from past:
6:6
Have they not seen how many generations We destroyed before them which We had established upon the earth as We have not established you? And We sent [rain from] the sky upon them in showers and made rivers flow beneath them; then We destroyed them for their sins and brought forth after them a generation of others.
I think humans can achieve much, we are surprised by the architecture and construction skills of past generations while i am sure they would be surprised by our technology, from mobile phones and e-mail to airplains and robotic legs. Do jins help in these things today ?
Or past generations used to be less smart that they needed help ? Someone said in a study:
What is important is how our minds differ from those of people 100 years ago, not whether we label it “smarter” or “more intelligent.” I prefer to say our brains are more modern.

The skills are not a problem with humans, but the inner exploration and sane spiritual development.
And Allah knows best.
