Soon the computer data stores will succumb to manipulation and tampering as well.
Soon? Try already did. The only advantage the internet has is that there is so much stuff thrown out there that you can find good stuff yourself if you know how to filter it.
Which is what schools should have been teaching students all along. Students don't need to be taught to go look something up, they can figure that out on their own. Knowing enough to tell valid information from non-information is quickly becoming the single most important knowledge skill there is.
Unfortunatly, schools often gloss over or ignore this topic entirly. Most teachers don't like teaching students to question the validity of authority, since the first thing they question is the teachers.
