I understand why many people are upset that their iPhone 15/14 Pro/14 isn't getting AI features at this point. However, this situation could actually be advantageous. Here’s why:
First, you have one of the newest iPhone models with a large amount of RAM, so it won't be slowed down by resident AI processes. Many people who don't want AI features, viewing them as intrusive, may prefer to buy your high-end phone on the used market because it’s updated but not overloaded with AI.
Second, there are scenarios where you don't want a memory resident AI such as this. Some companies (Elon Musk and Tesla) are stating that they will not allow phones with memory-resident AI in the workplace. They will require employees to check these iPhones at the door. Perhaps older phones will get a pass. This may create a situation where your iPhone is more desirable on the used market BECAUSE it lacks the AI. As a parent I also understand some don't want their children becoming involved with this tech just yet. They may seek phones like yours, too.
Additionally, those of us with iPhone 14 Pros can choose not to upgrade and save money. If you really want AI features, consider subscribing to ChatGPT directly. Their full-featured AI service is much more powerful than the lighter versions offered on phones, which mainly promote their own services. The best features of ChatGPT are only available through a paid subscription. AI on the iPhone will be relatively basic for at least three years, until you likely upgrade anyway.
Lastly, a coworker made an excellent point. There is a lot of competition between different AI companies, and they are increasingly offering bundled packages which include, for example, 1 TB of data for storing your photos, documents, and videos. You might determine it more fiscally smart to purchase one of these services and not pay more for iCloud, while you take advantage of an overall better AI experience.
It's my belief that Apple (like with Stage Manager) will open AI up to other phones after the initial sale of the iPhone 16 models. Samsung sold their S24 and claimed older phones wouldn't enjoy AI features, only to renig 2 months after sales began. Apple already appears behind with AI, and the technology is moving so fast that it may not wait around for Apple to fleece its customers for another year or more. Apple needs the data.
So, keep your phone, save money, or spend less than an upgrade would cost, and enjoy a monthly subscription/bundle including a superior level of AI directly from the company that created it. You do have options.
