Re: Can you guys please help me find this book???
I doubt these are it since they weren't written for children, but here's one possibility published 10/1/1986. In the book July 20, 2019: Life in the 21st Century
Arthur C. Clarke looked ahead exactly 50 years from when man first landed on the moon and made quite a few predictions. One I recall is all babies will undergo extensive genetic testing to sort out which weaknesses and strengths they have, partly to improve health, partly to guide them in directions suited to their natural talents. This might make a great BookTalk discussion in July of this year!
Another less likely candidate is Optimism One The Emerging Radicalism by F.M. Esfandiary
. I read that book in the 70's and as I recall, as the title indicates, it attempts to break down pessimism and details how wonderfully awesome the future will be. It's on my list to re-read to see how accurate it was. Published in 1970.
Other than that, you could look through old copies of Popular Mechanics magazine, which frequently included articles about future tech, not sure if they still do...
