I strongly disagree, for three reasions:
#1: Just because we have eSIM cards and bluetooth, dosen't mean pSIM (phisical SIM) cards and wired headphons are obsolete! It's good that the iPhone had bluetooth and eSIM, but it's bad that the iPhone removed pSIM and the headphone jack.
Apple hasn't eliminated the ability to use a wired headphone; you merely need to plug a dongle into the Lightening port.
From a design perspective, eSim makes it possible to have better structural integrity and saves space. For the user, it allows multiple SIM cards as well as the ability to active a plan without having to go to a store or get a SIM card in the mail. I bet 90%+ users never have an issue with eSIMs.
#2: I don't like your "the future" adatude. New technologies are not automaticly better than old (conversly, old technologies are not automaticly better than new). PSIMs and eSIMs are diffient tools. For some people, the pSIM is the proper tool. For others, the eSIM is the proper tool. There's nothing wrong with that, different people have diffient use cases.
I agree, different people have different needs. However, from a manufacturing perspective, if the gains of a choice outweigh the potential lost sales then you make the change. For most users, the loss of a SIM card will have no negative impact.
I would not be surprised if carriers pushed for eSIMs since it saves them money by not having to stock and ship SIM cards. I can also see the day carriers send out mass promotions, as eSIMS become the norm, with a QR code that says "Try us for x days for free..." as marketting campaigns; since they have already used them for such promotions on a more limited basis.
#3: If Apple included headphone jacks and an SD card reader, fewer people would buy AirPods and iCloud. As As @lartola said, it's a marketing trick.
iPhones and iPods before that, never had an SD card reader, so the iCloud argument is irrelevant. But if ou want to consider its impact, it likely would increase demand for iCloud storage since iCloud is a backup and synch service; increased storage via an SD card would only increase demand for space to synch and backup.
Bluetooth was becoming the standard for headphones long before Apple removed the headphone jacks. People do not like the cord and its limitations when using the device, such as being able to leave your phone on a desk or in a briefcase and still listen to music, answer calls while you walk around. If wired headphoones were still popular you'd see a lot more attached to iPhones via a dongle.
Don't misunderstand me, I'm not saying that iPhones are all bad. I have an iPhone for a reasion! As someone with an iPhone and two Android tablets, I know that there are atvantiges and disadvantages to both systems.
Sure, all systems have pros and cons and you should buy what meets your needs.
Do I like all of Apple's design choices? No, but I can see why they made them.
