I wonder what this stretching means for space quanta?
Can we "stretch" the energy quantum?

I have no idea (yet ;-).

In the article time has been reported to be quantized too -
only then the "cellular automaton" vision and the Ca speed limit 
make sense.

Probably many will do, but would there bee a guarantee
that none can lead to switching off the entire computer?

But all this is a speculation much more far-fetched
than the wildest Kyle ideas, I am afraid... ;-)
