I don’t just predict a lot of stuff on this site, I also live my life accordingly. For example, I never delete email. Email is so small in terms of disk size that even if I let it build up, hard disks increase in size faster. I still remember my first PC back in the late 80s had a 40 meg hard disk. Today my phone has many times that.
This matters because we are generating digital content at faster rates and the content is of higher quality (thus takes up more disk space). There are various services online (such as Dropbox) that lets you store a certain amount of information for free or very low cost but Amazon.com just blew them all out of the water.
They just introduced a new service called Amazon Glacier. You can store as much data as you want for $0.01 dollars per gigabyte. Naturally there is a catch. You can only retrieve a certain percentage of what you store per month before being charged for it, and the retrieval process takes between 3-5 hours so it’s not quick. Still, for long term storage you really can’t beat it.
I can foresee a time in the near future where we have wearable electronics with cameras and microphones that are always on. These will then stream our “life-stream” to long term storage like this. We will be able to essentially archive our entire lives. I know that might not seem like a big deal right now but there will arise a whole ecosystem of software that will allow you to do new things with your data that we can’t even foresee now.
Of course there are implications for education. Memorization goes right out the window if you can just do a search of your life stream. So do tests. The whole idea of what we learn in school will probably have to be drastically revised.
Don’t worry though teachers, you probably have about 10 years or so to get ready for that.
