Peter doesn’t invite us to speculate about timelines, but to examine our lives:

What sort of people ought you to be in lives of holiness and godliness? [2 Peter 3:11]

Holiness, here, is not withdrawal from the world, but alignment with the world to come. It is a way of living that reflects the reality we are moving toward. A life that anticipates the day when righteousness will finally dwell on the earth.

When we live this way, our lives become signposts. Small glimpses of a future reality breaking into the present. We are not perfect, but oriented in the right direction. -  Sebastiaan van Wessem, The Future Pulling Us Foward
