I think your ask (prediction of the future without bias/assumptions from the author) is basically impossible. You can't predict the future without making assumptions.
But a somewhat realistic, not completely dystopian sci-fi book that made the rounds last year and that I think is worth reading is Kim Stanley Robinson's Ministry for the future. Most of the science and economics in there are relatively sound, but it is still pretty much a best case scenario for humanities next 100 or so years.
