Based on what is happening to our society today, I have a prediction.

I forsee the entire world becoming nothing however 1 big kindle! That almost is happening now.

But, there are still some things that have a human touch, such as a central heating plus cooling system. The control units are becoming kindle! Like with the invention of the smart control unit. But still, there is something human about it. What I can see happening maybe 20 years from now, is that everything, including central heating plus cooling systems, will be alive plus have a mind of their own! I certainly suppose that is a real frightening thought! Imagine if your central heating plus a/c method decided to have a malfunction, plus was either over chilly or over heating your house! You would not be able to stop it, you would not be able to control it, but you could possibly get killed! The only way to stop the thing would be to destroy the central heating plus a/c method with a sledgehammer or something! This is a tale straight out of some sci fi or horror film! But hey, suppose about it. This could entirely happen if things don’t slow down with technology. I have not been a fan of all this advanced technology for this easily reason. I genuinely hope our little sci fi fantasy here does not come true! If it did, the people I was with and I are all doomed. Worse than it seems at this easily moment in time. Think about it.
