According to Mr kaku ENGLISH will be the language of a type 1 civilization.
The language that people first spoke in ENGLAND.

YEAH RIGHT MR KAKU!

Take the word Devil and find what it means in ancient Greek and from which words it is consisted.
Then you will get why in most debates there should be not a civilized manner of discussing stuff and that it always has to be division and eternal argument so efectively a polarisation effect has to settle in and the two sides become entrenched in to their beliefs. When polarisation occures there are other forces at work in the human psyche. Maybe the voices of some distant type whatever civilizations that Mr kaku and many like him had failed to identify, and those civilizations that came but are not completely gone YET! Though we are in a good path to be riding them out completely!

Pitting everyone against each other it seems to be the modus operandi. This is why Mr.kaku has to be so "right in your face" every time. That's why his army of followers, those "science" people are conditioned to be so intolerant of other thought systems. They have to behave like radicals to defend their little precious truths that are really based in NON FACTS and are in major ways carefull conjectures and assumptions. Paper towers waiting to colapse by the slightest breeze, creating a huge paper Kingdom of forced obediense and indoctrination that is effectively carrying the world far away from REAL logic and FACTS about the everyday happenings all around them and HOW life REALLY works.
IT HAS TO BE THIS WAY! So another system of REAL lies and deceit will have to settle in once the time and situation will be right.

First they make you to live in paper towers then these voices of the beyond powerless in reality are gaining strength, time by time, lie upon lie, deceit upon deceit, generation upon generation, enlightenment upon enlightenment and as your protective walls of the paper kingdoms you chose to dwell, are thining out so it's much more easier for them to be destroyed even by the mere presure of your own furious breath as you shoot angry words back and forth with each other defending one lie with another.

THIS IS HOW MR. KAKU'S TYPE ONE CIVILIZATION THAT WILL MAKE IT'S PRESENCE KNOWN.
A non force, coming to bring down your paper kingdoms.

These all must come to pass

because men know nothing but building useless paper kingdoms...
