Well, in my opinion, I guess this can be resolved when your IOS is updated to its latest version
It can't. This exploit affects the bootrom, which is read-only. There is no way to patch it. It would require Apple to recall every device from iPhone 4 through X and perform a hardware upgrade, which is obviously never going to happen.
It always surprises me how willing people are to place their entire lives on their phones in a way no one would ever have dreamed of a generation ago.
Complete sacrifice of privacy for the slightest convenience. I'm amazed that people are willing to bug their own houses on behalf of the government with Amazon Echoes, Google Homes, and similar devices, so they don't have to push like 4 buttons to turn on some music.
This is typical Apple support. When a product is only but a few years old, they declare it obsolete and don't bother with updates.
This is true, and Apple are particularly bad at this. Not just stopping updates and leaving old devices vulnerable, but actually deliberately slowing older devices down so users get frustrated and upgrade sooner. It's particularly immoral behavior. Having said that, I don't think this is what's happened here. It would be fairly stupid of Apple to know about this bug and leave it in, since it allows users to bypass their lack of updates and install their own custom software.
