Re: [ossig] A new revolution in the pipeline?
Yeah, I also thought the 'end of filesystems' bit is
nonsense. Also 'files will remain permanently open'.
Why? What about locking / concurrency issues? What is
the difference between an open and a closed file, anyway?
The trouble is, will this technology scale as well
as DRAM, at such low cost? It's one thing to say
'it's possible to have
an always on PC', but it is already possible with flash
RAM - just add 512Mb of flash-ram to your 512Mb DRAM
PC, and get it to write to flash when you wish to 'hibernate',
and it should only take a few seconds (???) to come back
on. But the trouble is, flash RAM costs 10's or 100's of
times more per bit, so realistically, nobody does it.
By 2005, when they are saying this kind of thing could
be ready for mass market, DRAM will be at 0.065 micron
or maybe down to 0.045 micron, and we'll all be buying
1Gb, 2Gb, 4Gb DRAM modules (especially since 64 bit
will be well established by then, fuelling much more memory
hungry apps).

The implications are interesting to say the least. Power requirements for mobile/small devices would drop quite a bit, I think. Couple that with the ongoing effort to bring small-scale fuel-cells to the masses, are we on the brink of another computer revolution?
I'm not so sure about the 'end of filesystems' though. In unix, everything is a 'file' so...
