The writers and commentators of today tend to fall into niche categories or just write fiction. There is Nicholas Carr's and Douglas Rushkoff. The latter even wrote a book called Present Shock. Most people I can think of are also of the past such as Vinge, Marshall McLuhan or Freeman Dyson (who came up with the idea of the Dyson sphere, not the vacuum) who were also brilliant. McLuhan is a joy to read or listen to. He has several interviews on YouTube. Esther Dyson (Freeman's daughter) and Nicholas Negroponte were others I read growing up along the lines of Toffler. I remember the latter's Being Digital as being profound at the time but passe in today's world since all of the marvels of the future he talks about came to fruition. Negroponte also came up with the One Laptop Per Child which lost it's relevance in a world of smartphones. Others I thought of were Neal Stephenson (his non-fiction works are awesome, especially In the Beginning... was the Command Line and that book-long article he wrote for Wired about wiring Cambodia). Stephenson's fiction is great too and puts William Gibson to shame when it comes to cyberpunk, but Gibson wrote his prior to the PC era. Rudy Rucker was also quite good at the time but his best non-fiction works such as Infinity and the Mind (a must read for you math geeks) are out of print. I also liked The Tao of Physics by Fritjof Capra a lot growing up. I looked on Goodreads for authors that are similar to Toffler and while I recognized a couple of them I didn't see anyone worth mentioning. Toffler's works were mostly dated after the mid 2000's, but predicted the consumer as producer (pro-sumer) culture we live in today and Revolutionary Wealth described how we would make a living with services like Patreon and GoFundMe in such a society. I recommend everyone read The Third Wave. It provides great historical context for the present machinations of society, the media, and the political machine controlling the masses. Powershift discuss the shift of power to the masses and is also good if you like the idea of the death of the establishment. Other people that come to mind are Nicholas Carr, Douglas Rushkoff, and Ray Kurzweil.
