Technology has changed, people have changed

Technology has changed a lot over the last 30 years.  Here is a list of what I consider significant:

1) The spreadsheet created an ability for a normal person to use a computer to do arbitrary complex calculations and give an answer.

2) Standardized widely available software made sharing documents and information by normal people easy.

3) The internet with a standardized information transport protocol became available to normal people at an affordable price.

4) Google won the information search provider wars and reached a critical mass opening the world's information to normal people for free.

5) Authors, industry experts, universities, speakers, TED, etc. publish materials, research, curriculum, etc. on the internet – free download for normal people.

6) Social media and other outlets provide hosting and content management for any normal person who wants to write or publish anything.

7) Hand held devices remove all barriers of access to the new world for everyone; except one barrier: ignorance.

I think this is significant; who would have predicted "ignorance" to be the barrier to entrance into a free global resource network?

Surely that barrier doesn't affect a majority of people?  Well, 30 years ago it didn't.  Unfortunately, now I think it does, in the US anyway.

How can I make a difference?  The "to be or not to be" question of our generation.
