Exponential growth is impossible to sustain for any appreciable
length of time as a practical matter. The fact that current growth is
exponential means that in short order we can expect it to abruptly halt.
But this is not the reason PC’s will never have gigabytes of RAM.
The reason is simple. Somewhere in the 50 to 200 megabyte range, all
applications, (or at least their active portion), will reside in memory.
Doubling memory may allow the entire set of applications to reside in
memory, but the performance gain will be small. The larger the memory
capacity, the smaller the gain.
As a result, additional RAM memory will not be added.

And how many more years before the count of bits is equivalent to the
number of silicon atoms in earths crust?
Does exponential growth confuse you?

How sad.
