I'd say convenience. Everything becomes so convenient, nobody does anything the hard or challenging way.
That's right - and it's with challenges that we gain a sense of accomplishment and fulfillment. An now, due to the increased convenience of everything, fullfilment is being replaced by apathy and indifference at an alarming rate.
We're at the point where people don't even push or pull doors open anymore - they go to the door for the handicapped, and push the damned button.
At this rate, it won't be long before people demand a button to automatically wipe their behind after going for a dump.
