For you....not to the rest of us. Even if the headphone jack stayed, you'd still have your wireless option. I don't understand all the complaining about it.
My point was that claiming that the optical drive has a successor but the headphone jack doesn't is a binary statement that is simply not correct as such. The need of users for an optical drive decreased over time, the same way the need of users for a headphone jack is declining over time.
Your 'even if the headphone jack stayed, I'd still have Bluetooth' applies in exactly the same way to the optical drive: Even if the optical drive stayed, I'd still have the download option (most use cases of the optical drive involved ripping DVDs and CDs and installing software, something nowadays overwhelmingly done via downloads). And the same way an external optical drive allows one to use optical disks when one still needs to, the (external) Lightning to headphone jack adaptor allows one to use wired audio devices.
On top of that, the Lightning Earpods provide a successor to the headphone jack for most usage situations (ie, most of the time somebody listens to audio on an iPhone via 'headphones', it'll be with the headphones shipping with the device and most of that time, people will not be charging their iPhones).
And 'the rest of us' implies that I am an extreme exception which you know isn't true. You just need to look at the success of Airpods and how the marketplace for Bluetooth headphones has exploded over the last couple of years with now probably over a dozen different in-ear wireless headphones and Bluetooth versions of most over-ear headphones.
Note, that in all the above, I did not say whether it was a good or the right decision for Apple to remove the headphone jack with the iPhone 7, I am just dispelling the myth that most people will be stranded without it, ie, that there is no successor 'technology' when in fact there are three of them: 1) Lightning Earpods, 2) Bluetooth headphones or speakers, 3) Lightning to headphone jack adaptor.
