Socrates was worried that writing, the then new invention, will cause forgetfulness.
> The people who invent something new, create a new tool or technology, are not necessarily the people who are going to understand what the social impact of those inventions will be.
>> And so it is that you by reason of your tender regard for the writing that is your offspring have declared the very opposite of its true effect. If men learn this, it will implant forgetfulness in their souls. They will cease to exercise memory because they rely on that which is written, calling things to remembrance no longer from within themselves, but by means of external marks.
>> What you have discovered is a recipe not for memory, but for reminder. And it is no true wisdom that you offer your disciples, but only the semblance of wisdom, for by telling them of many things without teaching them you will make them seem to know much while for the most part they know nothing. And as men filled not with wisdom but with the conceit of wisdom they will be a burden to their fellows.
I have more RAM than I need, and just the other day I set up a RAM disk to put my /tmp directory on. My comic reader unpacks huge rar and zip archives into /tmp at every run, and I don't want it to wear out my SSD. I put this line in /etc/fstab:
none /tmp tmpfs defaults,size=4G 0 0
It works like a charm. And in the worst case, if I run out of RAM anyway, it readily swaps out.
