Well if you want to be completely literal, then you’re right. It also isn’t literally a Tandy 1000.
But if you actually comprehended the article, the author said that you use your phone to perform all those functions. The iPhone can replace all of those functions you listed. It is water resistant and has a speaker. It does not have an AM/FM station but most broadcast radio stations also have a live stream that you can get in your phone. The iPhone came with earbuds when this article was written. It had a calculator app on day one, and it’s just fine. You don’t have literal CB but you can use a variety of apps to communicate with voice in real time. You can’t play the literal CDs but you can’t play the literal .wav files on the CDs.

So not the same function, got it.
As for your last example, you might as well replace "iPhone" with "tape deck".
iPhones did replace tape decks. The mini hi-fi in my living room, my car stereo, my tape and CD walkman, all are now either bluetooth recievers for smartphones or play audio directly from the smartphone.
The function wasn't "playing tape" or "playing CD", it was playing music or audio books.
