You mentioned 8K video, however it has been a problem since apps like Filmic Pro have had the ability to record in 150mbps streams.
Last year it got worse with the 13 having ProRes video, which takes a staggering 5 gigabytes per minute if shot in 4k30.
Yeah, I read a number of stories of filmmakers using iPhones for 4k and having to basically have a stack of them to hand off when they got full, with a messy laborious back-end to offload the data. It is a mess, as-is. That's why I suggested that, if they offer 8k, it makes it an even shakier proposition for them to not offer some faster transfer method (USB-C, or some sort of Lightning+, which seems foolhardy at this point, but who knows, or some crazy new wireless transfer method). I think we're on the same page.
I really do believe that this comes down to money for Apple. They license the cables, people pay for the right to manufacture the lightning cable, as far as I understand it they need to purchase a license for the tech.
I don't know how much of it is
directly money for Apple (cable sales or royalties), and how much is
indirectly money for Apple (something like, "we used 30-pin for 10 years, we designed Lightning to last 10 years, users
hated the change last time, we're reluctant to make changes that will make grumpy users, because grumpy users buy less phones")... Unfortunately, professional filmmakers are a minute fraction of their customer base, and Apple is likely looking primarily looking to cater to people who will get really excited about 8k and then only ever use it to film a couple of 3 minute clips (but, gee, they've already got a bunch of Lightning cables/accessories in their house and car)... It will be interesting to see how things play out.
Personally, I wouldn't mind seeing Apple drop having an actual
jack, and go for something like the smart connector they have for the keyboard on the iPads (just a row of contacts and a magnet) - let it just do charging and crazy-fast data transfer. But, I think the combination of already having the round "Magsafe" wireless charging connector, and the looming "thou shalt use USB-C" regulations, I suspect USB-C is more likely.
I am an Apple user 100% in my workflow and do not even own a Windows device any longer, or any Android. I still call out their BS shenanigans on the inability to upgrade RAM and SSD's on desktop devices, and the Lightning adapter should have gone away a long time ago.
For what it's worth, my last PC ran WinXP, I've been entirely a Mac user since the mid 2000's. Coming at it from a different angle - I'm a Unix user at heart, and the Mac has been the nicest Unix workstation/OS combination for many years running. And my last couple MBPs all got RAM and SSD upgrades that made them last many years (upgrading to configurations that Apple didn't even offer when they came out) - my new MBP, on the other hand, has a ton of storage
because I know I'll never be able to upgrade it, and I find that pretty annoying (I mean, I like all the capacity, but I didn't enjoy having to pay for it up front).
