This is not the future, this is nothing but a giant step back! The beauty of the headphone jack is that it's an old open standard. You can still use headphones from the 80ies with a device from today. You can use the same headphones with your phone, Nintendo 3Ds, PS Vita, Laptop, Tablet, Desktop, Camera, ... everything. And it's rather small actually. Nobody cares if the iPhone is 0,5 mm thinner or not. In fact, many people wish for a phone that's a little bit thicker, so you can hold it better.
So how is it "the future" if you potentially need proprietary headphones for every device? If you need to bring 3 different headphones when you travel?
How is it the future if you can't use your headpobe for an unlimited amount of time, but need to charge them every 5 hours? What will you do an long plane or train trips? Or when you use your headphones while you work? Bring a power bank and connect them with a cable to the power bank after 5 hours? So you actually need to carry more, not less? And still have a cable?
Next, we all know, batteries get weaker over time and eventually fail after a few years. Like I said, you can still use headphones from the 80ies. I doubt the AirPods will last more than 3 years. Let's fill the planet with more toxic waste. Apple should be put on the bottom of every green company list for this.
Next, people will lose these. We lose stuff all the time, small things that are loosely attached to your years will eventually get lost. Yay, more sales for apple, even more toxic waste for the planet.
I hope these Airpods and the new iPhone will not sell well, both as a message to Apple and as a message to other vendors. This will only benefit all customers. People, please don't buy every crap just because it's new. Let me close with a reference to Fight Club: "you are not your cell phone."
