I've noticed a decline in my own spelling and ability to write in cursive. My "smart phone" auto corrects words that I have spelled correctly and I have to manually input the word into the key touch system. It drives me crazy.
So I can see why the decline since people are just trusting the devices we have know better than we do?
Also, I really like math. Not more than 6-7 years ago I could work out some decently complicated problems in my head pretty fast. It was this year I noticed that I had stopped doing that because my phone does it for me. I was talking with a client about it who is 35 yrs plus my senior and she too said that she has noticed that basic math was harder on the fly since the rise of smartphones.
I was talking with other folks much older than me (which is my normal for the simple reason that it seems, over all, they are more educated) and all of them said that Latin was taught in middle and high school when they were young. I felt/feel cheated somehow. Now its a course in college that one chooses.
I remember when talking in "Ebonics" was a joke and then it was as if it became a statement of 'style' and other retard reasoning I wont go into here. OH NO YOU DI'-ENT. Ugh.
Personally I appreciate when some person genuinely points out to me when my wording is wrong.
The internet is loose for me, meaning I get in a hurry sometimes, allow myself to multi task and then not pay attention to precisely how I'm wording things.
