Am actual doctor. I think we're both closer to and further away from a Tricorder than you think.

Point of care ultrasound has been booming for the last 1-2 decades. There are now cell-phone sized wireless probes you can easily put in your pocket and do multiple diagnostic scans on the heart, lung, belly, etc with the caveat that you have to be adept at both obtaining and interpreting ultrasound images which certainly takes a lot of process.

There are devices about as big as 2-3 cell phones (think label maker or portable speaker sized) which can reliably run a whole panel of common blood tests including electrolytes, a blood gas, and hemoglobin on a 1-2mL blood sample in <5min. We also have dedicated point of care A1C devices, PT/INR devices, and probably some more I don't know about.

I don't think we'll ever have handheld xray/CT solely due to the significant radiation risk the operator would experience, even if the technology could be miniaturized.

I don't think handheld MRI will ever happen either. The power requirement alone for the magnet strength needed is immense, not to mention the dangers of the magnetic field in some random unsecured area and the length of normal scans makes a handheld device impractical.

I don't think we'll ever have "bloodless" comprehensive blood testing. There's only so much you can do with spectroscopy, and some things like electrolytes are in dramatically different concentrations between the cells and the blood so scanning through skin would likely dramatically alter readings.

TLDR we are actively miniaturizing some medical technologies. There are physics limitations in "handheld-izing " most non-ultrasound diagnostic imaging, and while we've certainly made great progress in point of care labs, I don't think we're going to get a device that can measure those things without a blood sample.

Mifepristone has no role in the treatment or prevention of ulcers, only misoprostol is used in that fashion.

All remote based typing is awful, T9 included. I can't speak for everyone, but I can type with swipe gestures on a virtual keyboard via remote faster than I can input T9 text. I'm unaware of any stock remote for a device with a full keyboard. I would argue Apple has text entry perfected at least as well as any other major manufacturer. You have virtual keyboard entry, solid voice-to-text, and it can be configured to push a notification to your iOS device when you enter a search bar which will auto-open to the remote app and pull up the keyboard. Because of this feature passwords can also be autofilled from Keychain to make logins easier.

You may personally prefer T9, but I've never seen anyone in the last decade input anything into a TV via T9. And you're asking why it doesn't have voice input, when it does. You admit to having never used an Apple TV yourself. I hate the idea of app-only interfaces features, but this isn't a case like that. Maybe you should understand the features of a product before you call it "fucking stupid".

I self host a lot of shit, but after almost a year of using Obsidian I finally paid for their sync feature for one reason: iCloud sync to iOS is painfully slow.

I was sometimes waiting 30-45 seconds to jot down a note just waiting on the app to open with iCloud sync as my backend. Now, with Obsidian sync, the app is ready-to-go in seconds.

Now if you're only going to be using on desktop, I would definitely consider a git-repository based sync, but if you're gonna use mobile I'd recommend you at least consider Obsidian Sync
