A couple things come to mind right off the bat. The first, that has already been mentioned, is that I'm not even remotely interested in trusting the cloud so absolutely.

I just posted about roll your own VPN's, and I'm far more likely to be willing to temporarily project enough awareness to undertake certain actions requiring remote drones with my own personal hardware as an entry point.

Also, given nascent technology, we aren't likely to need headsets or visors for very long. EMF is shown to impact neurons, and fully characterizing means of 'wireless' BCI is prolly just a matter of time and engineering.

This would enable all the senses to be emulated, spoofed, augmented, and etc., and we wouldn't look so goofy while we were doing it.

Also, the author's trust in technology is charming, but unwarranted IMHO. I am confident in hardware failures persisting for the foreseeable future, and I've got enough HD's and phones laying around with broken screens and bad sectors that I intend to salvage the data from (someday... soon...) to make the point that I really am not gonna just abandon my meatsack anytime soon.

Also, I have plans for meatsacks. I don't think we need to abandon them to become immortal, and in the near term. I reckon I can see 3D printers making that happen very soon, by using them to print us up some fresh parts as we need them--no doctors, pharmaceutical, or insurance companies required.

We need to expand on the tech that makes organoids a thing, and robotic surgery is being enabled as we speak.

'Siri, pop me in a fresh liver. I hate this hangover!'

Consider that we're already printing and growing human ears etc., on mice. Computer assisted/robotic surgery is also already a thing, as are organoids. It's no great leap to combine them and make an app for it.

This is coming. Uploading to the cloud and arkanciding your meatsack? Well, there's plenty of folks I can be willing to allow to do that. I ain't one of 'em. Given the kinds of folks that so easily trust the enemedia and faithfully carry out their pogroms and vote for their politicians, I can actually see that those folks being early adopters of the author's plan would solve our political woes--especially if we also add the psychopaths and megalomaniacs using them as weapons against us to the plan a bit more 'persuasively'.
