Ok, I am old. yes I remember actually reading the whole set of manuals on multics.
time sharing is a concept i am familiar with.

then apple put a pc on every desk, next to a chicken in every pot.
the 1990s ensued with a vigor reminiscent of the prosperity following the new deal
(Something FDR ((Franklin Delano Roosevelt)) did 8 decades ago)
desktop publishing, desktop wysiwyg, desktop sex was everywhere

then networking mutated into the internet.
thick 10mbs coax cables became hair-thin terabyte/s fiber
we got vnc, rdp, etc.

then moore's law gave us supercomputers on a chip.
an os could be run within an os within an os-all on the same computer that fits in your pocket.

but with all this power to create a whole virtual reality in your pocket, we are migrating back to time sharing. we are making our oses sandbox everything.
we have antivirus and antirootkits using more cpu cycles than the apollo moonshot.
it is as if we are all in the deathgrip of an evil empire that wants to suck out our brains and turn us all into zombies. we are so possessed with fear of the 'evildoer' in this 'cyberwar' that we are saying
'please do all the 'important stuff' on the mother ship and just show me the pictures'

so here is my question- what are the real uses/benefits of the following virtual/distributed computing setups

1) big computer in mother ship
- vnc on a thin client/desktop pc to mother ship

2) big computer in mother ship
-running vmware with multiple instances of oses that can be started up as computing demands increase
--vnc on thin client

3) big computer in mother ship running
-vmware with multiple instances of oses that can be started up as computing demands increase
--running pcoip on top of that to bitblast graphics across the net
---vnc on thin client

4)distributed computing network(labeled a) instead of big computer used in scenarios 1,2,3 above to give 1a,2a,3a

5)distributed file system(labeled b) added to above 6 scenarios above to give 1b,2b,3b and 1ab,2ab,3ab

which of the above is the amazon s3 cloud?

why do we want to clog our networks with all this crap that can be done on our desk?

do we REALLY need to be electronically interconnected to such a degree?

when will we reach the point that we won't need to talk to each other-in other words how much networking capacity in yottabytes/s will we need to implement scenario 3ab for 10 billion people?
