This post brings to mind Arthur C. Clarke's three adages.

• When a distinguished but elderly scientist states that something is possible, he is almost certainly right. When he states that something is impossible, he is very probably wrong.
• The only way of discovering the limits of the possible is to venture a little way past them into the impossible.
• Any sufficiently advanced technology is indistinguishable from magic.

I often think about what technology will look like in the future, but the truth is there's only so far your imagination can take you. Some things need to be experienced empirically before we can conceptualise how they could evolve, so while we might be able to conceptualise about what technology will be around in 20 years, to imagine what will be here in 100 or 1000 years, we may need the experience of living with technology from 50 or 500 years in the future.
