Drinking too much water in a short period of time can indeed definitely kill you.
As far as all this recently additional RF energy bouncing around us is concerned, it would be prudent for us to go slow, and let science and medical research determine safe thresholds for humans and animals alike, lest we end up with epidemic proportions of various types of cancers 20 to 30 years from now.

No. Let's do quick napkin math. And take Wi-Fi as an example.
iPhone 7 5GHz band working on full power emits 128 mW.
USB type A port can provide 2.5W (500mA * 5V).
So if you would like to charge iPhone with iPhone using its WiFi signal it would take about 40 times longer than by connecting it to USB port. To this value you should add about 20% losses on AC/DC conversion (your battery requires DC but electromagnetic waves gives you AC in receiver coil). Also energy transmitted by radio waves diminishes very quickly with square of distance.
And double "no".
As for general "this is safe" vs "this is unsafe" discussion - it depends on energy and wave length.
Longer waves like radio, microwave and infrared are absorbed by human body - turn on classic bulb next to your hand and you will feel warm even before glass gets hot - those are infrared waves converted to heat. But if you bump energy it will simply cook your body cells. Therefore microwaves in ovens are not safe. The only reason why you can use oven without injuries is because it is screened. Check your microwave oven - it has steel walls inside and grounded metal net on the glass.
To summarise - EM waves are quite good in carrying information, they are terrible in carrying energy on low frequencies. You cannot bump frequency to UV, X-Ray or gamma because those frequencies can damage DNA, you have to stay below infrared. So if you want to charge phone remotely on reasonable distance in reasonable time - you will have weak, open microwave oven in your home
In order to charge a phone, a strong EMF is needed. There is a risk that this effects pacemakers and DBS stimulators. The strength of the EMF in house depends on the number of charging points. This should be investigated before the system is sold.
What I am thinking is they use a pad for regular charging and this in addition. We all know Apple wants to yank the last port at some point. Because they won't give the pad away it will probably be in the "premium" model so they can recoup the cost.
The other phone models will be the same as ever so you only have to pay for the pad and extra features on the premium model. It will obviously be a first gen product and improve over years just like wifi did.
People will hem and haw about how it isn't ready for prime time and then be refreshing their shipping trackers to see how many months they have to wait when it sells out in the top model. The only reason a person wouldn't want this feature as others have said is cost. Perhaps some people are concerned about health would be the only other reason you wouldn't want this feature.
I love the idea obviously but might sit back and let the early adopters pay the R&D a couple of years before I make the move to wireless charging. It needs a couple of years for the charge stations to be rolled out.
For that matter I remember back in the day when the entire internet itself was considered a gimmick.
Maybe they did, but didn't want to prematurely announce it ahead of announcing such a groundbreaking feature on-stage.
Or people saying if they go into a coffee shop or somewhere like it they would have to stay for hours to charge it up. Do they not see the point that any time they spent in the shop is time they can use it and it doesn't matter what battery life is?
So if I have to make a skype video call that will take let's say 2 hours... I can duck into a Starbucks or whatever. Once I am inside using their charging my battery life goes up while I do my business.
It baffles me as well how people just can not grasp the concept. Apple will probably have to remove the battery meter so people can understand there will come a time when it is no longer a matter of percentage. If you are getting more power in than what it is going out you can be at 2% all day and it doesn't matter.
What could be nice is if they make a charging block that also has no wires that is a fast charger. This would normally be charged by wattup and usually in one place. It wouldn't be necessary to use often so it would theoretically always be 100% charged and completely portable so if you do need it on the go.
Again the quick charge is completely wireless so you never forget to plug it in and it is always there for a stand by.
Thank god.
Hopefully Apple will make it easy for businesses to install these Apple transmitters in their stores so that from now on when you swing into a fast food place, coffee shop, even theme parks like WDW, then your phone will automatically start charging even while it's in your pocket.
If Apple pulls it off correctly it will revolutionize charging the same way wifi did for the Internet!

If Apple are going to be using this technology, i can see why they waited to adopt wireless charging, this could be really good and solve a number of issues such as forgetting to plug your iPhone on charge. I'm guessing that if adopted this will be used in the iPhone first, but it could later be adopted to iPad's, Apple Watch and maybe even Mac's. I would be very happy if this is included in the next iPhone (iPhone 8).
What works for you may not work for everyone else. What baffles me is that you are under the assumption that just because Apple may roll this out, that all/most businesses will invest in this infrastructure - in addition all other phone manufacturers would need to hop on board to make this technology ubiquitous. Will it be on public transportation, in cabs, at the workplace (as some people do conduct business in places other than the local coffee shop)?
As for removing the battery percentage meter, do you really think that people will be in range of a wireless charging emitter ALL THE TIME or even enough time for someone to charge their phone? Yeah. I leave Starbucks, at 2%, which I won't know because you think Apple should remove this information, and on my walk home, I can't make or receive calls because my phone battery is dead. It's not like there's going to be a federal law stating that all public places have to have wireless chargers...
Your dystopian view of charging wireless phones is a LONG way off - if it ever materializes at all.
Let's not even get into the chances of exploitation when connected one of the chargers. I obviously can't comment on this, as I don't know the spec, but I also can't rule it out either.

You are the smartest, most infallible, person I "know". It is a pleasure to even be allowed onto the same BB as you.

I can see this being somewhat how it goes. Apple has made it clear that they want to remove everything from the phone that they think is unnecessary. A port mainly used for charging would definitely fall on that list. The question to me is a matter of when. This year may be a starting point, but I think we are still about 3-5 years away from being completely wireless. I personally hate the idea of a charging pad that is associated with the current "wireless" systems. To me there is no point in calling it wireless charging if all that I'm doing is plugging a charging station in which my phone must be on instead of plugging the phone itself in. Some sort of charging pad or clip would be a solution for a mobile charger for a phone without a charging port though. I can see there being a ton of issues that need worked through still as well as the mentioned health concerns people will have and many of those issues won't truly be worked out until this type of system is in a large number of people's hands. It will likely be a technology filled with baby steps, as it already is. I'm sure if this system is launched, Samsung, Motorola, or some other tech company will have a competitive strategy against it, despite the easy solution being all manufacturers going on board with one system. One way or another, I think we are headed towards a future where we won't be plugging in phones to charge and eventually many other things will follow.

I think you'll find they all use the same radiowaves regardless. There has never ever been shown of any risk of cancer or anything you're thinking of from any of them.
The only thing that does happen is if you increase the waves to thousands of watts, it'd burn you (eg a microwave) it still doesn't cause cancer, it'd just cook you alive.

You could say that about anything someone is to the market first with. Lots of people are pushing forward with it, they are (one of) the first with a working example.
Exclusivity. But honestly not everyone is for sale. I'm unsure why thisnisbthebfirst thing some people go to.
One of many examples: Apple wanted drop box. They declined. And it seems like they're (drop box) better fornit.
and if you've been at home overnight, it would be wouldn't it...

Because research on radio waves has been done to death by scientists for 30 years, they know everything there is to know - they're not creating a new wheel here that has to be tested specifically for this.

Yes it is clear that "phone radiation" (as you call it) is not harmful. There are a thousand studies you can read on this online alone rather than just spouting off invalid scaremongering on a forum.
Have you been worried about radiation every time you went outside on a sunny day? For years....
He is right. It's all that matters. Being right matters, facts matter, bending truth or adjusting facts to not hurt someones feelings doesn't matter. Facts have no feelings, that's all that matters.
I like that idea. But with a 15 foot charging range, I'd probably need a handful of them to cover the house. Maybe a 'main' unit with WiFi and charging, plus some 'satellite' units with simply charging and maybe WiFi repeater/signal booster?
Given that Apple has removed the headphone jack on iPhone 7 models, leaving the Lightning connector with the double duty of charging and connecting wired headphones, the move towards wireless charging would be appropriate.
This seems like weak logic to me, Apple could hardly justify all the effort involved to implement wireless charging by claiming it is now easier to use wired headphones.
Why not just use wireless headphone ( that already exist ) and charge with the lighting connector instead.
Hence the reason why Apple may not implement this. Apple probably did consider this type of wireless charging, but after the Samsung Galaxy Note 7 fiasco, they dropped it for safety reasons.
