Why indeed!
I can envisage a situation futuristically where there will be no shops, nor bookstores nor banks nor chemists et al.
Neither will there be any postwoman nor tailors nor fishmongers.
There will just be one central warehouse somewhere. It will be a huge colossus of fabricated material perhaps where the memorial park used to be. When we want anything, no matter what, we will order it from the comfort of our own home it will of course be more convenient and needless to say it will be cheaper. We won't have to go further than our i - pads to identify and supply all our wants and needs. If you don't have an i pad you will of course be the lowest of the low and you will be excluded from society or whatever society will have become.
There will be no need for human contact of any kind as all this can and will be done electronically. It is something that we all have to look forward to.
