You don't have to be Einstein to understand this

Since October a message and set of photos including those here has gone viral on emails and blog posts with the following quote which is attributed to Albert Einstein.

"I fear the day that technology will surpass our human interaction. The world will have a generation of idiots."

I think the point is valid and the pictures are endearing [or pathetic or alarming?] and don't need to be backed up by the supposed authority of Einstein.

There is a further problem that there is no concrete evidence that Einstein ever said this. No source is provided. I did a search in The new quoteable Einstein and it yielded nothing.
In a similar vein see Out of all those quotes attributed to Einstein which ones are really his? How can you tell?

The issues this raises are similar to those in my earlier posts
