The thing with cloud and with anything related to it, anything that connects to the internet somehow... is that, unless it's open source and the servers decentralized, you are always trusting SOMEONE. Sure, Apple might make their best to ensure nobody – but them – have access to your data... but Apple controls all the end points. It controls the updates your iPhone receives, it controls the servers where this happens…

That's true, but also it should be possible to make an OS that people can trust without trusting you, and as users we should encourage movement in that direction.

I understand the sentiment, but it's impractical to live in a trust-less society. If you've ever had dental work done, you've put an awful lot of faith in a stranger pushing a drill into your head. Ditto for riding buses and bus drivers, etc etc. Trust can be abused, certainly, but it also allows collaboration and specialisation, and without those I doubt we'd have gotten very far.

I'm happy to trust many kinds of people, dentists included, just not the kind people who find themselves at the helm of companies like Apple and Google.

Better to trust many people narrowly (e.g. I don't trust the bus driver to drill my cavities) than to trust a small handful of people broadly (e.g. like Apple expects of their users).

It's sad to see so many discussions on security and so little on privacy. How about solutions that could combine both, such as homomorphic encryption for AI?

There’s not a single homomorphic encryption implementation out there which can do real world quantities of computation

Thanks. I wonder how long that service is going to last.

its been around a loong time

I wonder who Apple will be colocating with for data centers. And what the PCC chassis looks like for these compute devices (will it be a display-less iPad)?

Apple’s rich enough to build and own their own datacenters. Savvy enough, too. I’d imagine the chassis are custom Apple-NOC-specific M-chip powered servers.

So basically, a Mac mini.

It’s not about technology. It’s about their business. Apple generally engineers their business so that there isn’t an incentive to violate those access controls or principles. Thats not where the money is for them. Behavior is always shaped by rewards and punishments. Positive reinforcement is always stronger.

One hundred percent this. All these conversations always end up boiling down to someone thinking they’re being clever for pointing out you have to trust a company at the end of the day when it comes to security and privacy. Yes. Valid. So if you have to trust someone , doesn’t it make sense for it to be someone who has built protecting privacy into their core value proposition, versus a company that has baked violati…

That's a false dichotomy. You may have to trust someone but that someone could be something else than an opaque for-profit company.

Gotcha, makes sense :)

What makes you think that internal access control at Apple is any better than Google's, Microsoft's or OpenAI's? Google employees have long reported that you can't access user data with standard credentials, for example. Also, what makes you think that Apple's investments on chip design and OS is superior to Google's? Google is known for OpenTitan and other in-house silicon projects. It's also been working in secure…

That's becoming less the case. As Apple's advertising and services revenue grows and hardware sales slow, they have increasing incentive to mine your data the same as any company does. They already use quite a bit data on the location and content personalization front. I would argue that Apple perhaps cares about protecting your data more from malicious third parties (again like any company should - it's never good for FAANG when data leaks or is abused), but they are better at it (and definitely better at marketing it).

This isn't right. If you trust math you can prove the software is what they say it is. Yes it is work to do this, but this is a big step forward.

It's not fully homomorphic encryption. The compute is happening in the plain on the other side, and given the scale of models they are running, it's not likely that all of the data involved in a computation is happening inside a single instance of particularly secure and hardened hardware. I don't think it's reasonable for most individuals to expect to be protected from nation-state actors or something, but their claims seem a little too absolute to me.

Give me some examples of benevolent non profits that provide anywhere near the level of consumer services as a company like Apple.
