'My personal challenge for 2016 is to build a simple AI to run my home and help me with my work. You can think of it kind of like Jarvis in Iron Man,'he posted on Facebook on Monday.'I am going to start by exploring what technology is already out there.

Then I'll start teaching it to understand my voice to control everything in our home - music, lights, temperature and so on. I'll teach it to let friends in by looking at their faces when they ring the doorbell,' the 31-year-old billionaire posted.

"I will teach it to let me know if anything is going on in Max's (his daughter) room that I need to check on when I'm not with her. On the work side, it'll help me visualise data in VR (virtual reality) to help me build better services and lead my organisations more effectively," he further wrote.

His past new year challenges included reading two books every month, learning Mandarin language and meeting a new person every day."Every year, I take on a personal challenge to learn new things and grow outside my work at Facebook. The theme for his challenge this year is invention," he posted.
