The Facebook founder traditionally uses the beginning of each year to set himself a task - from learning Mandarin to visiting every US state - but he instead decided to replace that with longer-term reflection.
Writing in a blogpost, he said: "Rather than having year-to-year challenges, I've tried to think about what I hope the world and my life will look like in 2030."
The businessman suggested that by 2030, the world will "have the technology to feel truly present with another person no matter where they are, and scientific research will have helped cure and prevent enough diseases to extend our average life expectancy by another two-and-a-half years".
He also took the change to look back on his younger years, and discussed how social networking platforms needed to refocus their efforts.
He explained: "When I grew up in a small town, it was easy to have a niche and sense of purpose.
"But with billions of people, it's harder to find your unique role. For the next decade, some of the most important social infrastructure will help us reconstruct all kinds of smaller communities to give us that sense of intimacy again.
"Our digital social environments will feel very different over the next five-plus years, re-emphasising private interactions and helping us build the smaller communities we need in our lives."
