I want to make a prediction. I think in around 10 - 15 years, most of the people in the western World will own or think about owning a Virtual Reality Headset. I also think that digital Assistants like Google Assistant or Alexa will be more important in that context than currently.

For context: I own a VR Headset and use digital Assistants since multiple years. I also worked in a team developing a digital Assistant and seeing practical use-cases for AR in the past.
