I'm not **that** much of a snorter, or I wouldn't be here ;->
I'm still a secret believer in the Generalized Moore's Law.

Yes, yes, bring on the 3D packing, the fanouts, the connectivity, the
sheer number of active units. The smell from the oven is starting to make
me salivate.

Yes. Yes. Yes!

Call my lawyer. Call my stockbroker. It's time to upload ;-> .

Could you elaborate on that last sentence a bit? I can't quite make
out what you're saying here.

I'm very much looking forward to it (as are we all)!
