This Luddite has rather a lot of money invested in a professional grade audio interface. Replacing it with modern connectivity would be upwards of a thousand dollars. Ouch. And it works perfectly. Why am I throwing away hardware that I like and trust for the relentless march to the future?
Any recording interface more substantial than a headphone jack is wired. It's going to remain that way for a while. Audio is a quasi-realtime problem with a lot of bandwidth. Neither Bluetooth nor 802.11 are really reliable enough for the task, and won't be for some time to come.
Preserving investment in hardware that works, rather than making a risky expenditure on hardware that may or many not work (and will change process), isn't "Luddite". It's realist. We have the same problem with much more static tech, like ATMs and voting machines. The "one single port" dream you're spouting? I've heard that dream before. It was called "Firewire" back then. Another decade or so, and we'll be digging Lightning connectors out of our junk drawer and saying "Hey, remember this? Do we even need to keep this anymore?"
But this is where I get pragmatic. I know I have compatibility issues, so I'm looking at semi-retiring the MBP just for the heavy lifting and compatibility of audio, and maybe looking at what else can be done about photo editing. And a Chromebook for web browsing and other not-hard-work sounds better and better all the time.
