    I can understand a small difference, but a factor of 24?!?

    Bluetooth is largely garbage. Good enough for mice and keyboards.

    Well, that's what it was designed for,

    Where do you live? In today's world photos and videos are mirrored
    online from your smartphone to whichever cloud and then downloaded to
    the computer with 1 Gigabit/s without any intervention by the user.

    Fiddling around with BT or cables is very very old style.

    Nonsense. It is still explicitly a *slow* wireless technology,
    and it is designed as such.
    For fast wireless we have always had WiFi,

    its much faster now, and designed for far more than just mice and

    nope.

    For fast wireless we have always had WiFi,

    for entirely different scenarios, and with a much higher power budget.

    yes yet and has been for some time, which is why many access points
    have 2.5g-e (or better) wired ports.

    <https://www.extremetech.com/computing/184685-what-is-802-11ax-wifi-and- do-you-really-need-a-10gbps-connection-to-your-laptop>
    Letıs say we take the more conservative 4x estimate, and assume a
    massive 160MHz channel. In that case, the maximum speed of a
    single 802.11ax stream will be around 3.5Gbps (compared with
    866Mbps for a single 802.11ac stream). Multiply that out to a 4?4
    MIMO network and you get a total capacity of 14Gbps. If you had a
    smartphone or laptop capable of two or three streams, youıd get
    some blazing connection speeds of 1GB per second or more.

    In a more realistic setup with 80MHz channels, weıre probably
    looking at a single-stream speed of around 1.6Gbps, which is still a
    reasonable 200MB/sec. If your mobile device supports MIMO, you could
    be seeing 400 or 600MB/sec. And in an even more realistic setup with
    40MHz channels (such as what youıd probably get in a crowded
    apartment block), a single 802.11ax stream would net you 800Mbps
    (100MB/sec), or a total network capacity of 3.2Gbps.

    I absolutely detest that auto synching stuff.

    I love it. Totally painless photo management

    I want stuff to go where I put it and to know what I'm putting where.

    Me too. That it is all done automatically - using wi-fi - makes it even better.

    Just because I take a photo on one device does not mean I'm going to want it on another.

    I want it everywhere. As quickly as possible.

    I bet you don't even know where the file is.

    Of course I do.

    Is it on your phone?

    Yes.

    Your computer?

    Yes. I assume you mean Windows PC. A phone IS a computer. So is an
    iPad.

    Both?

    Yes.

    The cloud?

    Yes.

    All of the above?

    Yes.

    What if the internet goes down, where can you find the file?

    Depends on when “the internet goes down”. If its before I took the pic, then it is on the iPhone/iPad/whatever I took the pic on. When the
    internet connection comes back then it is everywhere.

    And where is it?

    Where it is supposed to be, with all my other photos.

    In the same folder on both devices?

    Yes. On way more than 2 devices.

    What if the folder structure is different?

    It’s the same. In the 21st century I no longer worry about “folder structure”.

    Have you now got stuff all over your computer's disk in different places
    you don't know about?

    No, all in the same place.

    What if you don't want another user of the computer seeing the photo you just took?

    No one else uses my stuff. Everyone in this house has their own iPhone/iPad/Windows laptop. And they have all of THEIR photos on all of
    THEIR stuff.

    What an utter mess.

    What total bliss.

    Computers should never ever assume what you want to do.

    No assumptions here. This is how we set it all up. None of this happens unless you set it up. So I could - assuming I wanted to - manually
    transfer photos over Bluetooth. I could do it manually over USB cable
    too.

    But why would I want to do it manually when automatically over wi-fi is available?

    Unless your house is broken into by a burglar or the police and they're all taken.
