You could have multiple SPAs in the same page but you don't actually do that in practice.
You do this not because this is simple, not to create a better user experience but so that you can have 100+ teams working on the site without them being stuck because every change needs to be carefully coordinated with everyone else.
If you don't have a few hundred people working on the frontend in many different teams, don't try this. This first and foremost solves the problem of coordinating and communicating between these teams by eliminating (some of) the need to do that. There is nothing to gain and a lot of overhead to deal with, if you're in a company without so many engineers.
In these cases the amount of money you spend on hardware virtual or otherwise is negligible. Depending on what you do it might just as well be a rounding error.
Additionally SQL as supported by some DBMSes (e.g. Postgres due to recursive CTE and window functions) is turing complete. That makes proving equivalency in general a bit challenging.
That's not a bug, that's a feature and the system working exactly as designed.
For example measuring the time of a=b with constant b tells you roughly how large a[:n] such that a[:n] = b[:n].
The only reason you can only ever turn right is because the light stays red, if it were to turn green you'd be allowed to cross the intersection in any direction.
There are also different rules that need to be followed when crossing the intersection on account of a green arrow than, if it were merely a turn right only situation.
The big difference they've made is that they've created tools to make integration with Voice Over so easy, that it's a no brainer to do what little work needs to be done to make an app accessible and to increase demand for it.
They've managed to turn a burden into something that has an obvious economic benefit for app developers.
Also I'm fairly sure that there is actually a good RoI. It might not be massive but in the long term having the monopoly on phones for blind people surely pays off.
How do you install independent app stores to begin with? Do you install them with he App Store? That would put them at a disadvantage similar to how Microsoft put other Browsers at a disadvantage with IE. Do you provide a choice then when you setup the phone?
Purely from an anti-trust perspective I can see why the idea of independent app stores might seem appealing at first glance. Thinking about this just for a moment brings up so many questions though and I don't see how you can possibly come up with satisfying answers that lead to good security and a good user experience.
Maybe it's just me but I find it completely impossible to sift through it. The search is completely broken, there is no catalog worth going through. The only think worth looking at are the lists curated by Apple but then again usually I'm looking for something more specific.
In practice the only reliable way to find a good App, is going to be searching with Google, reading reviews outside of the App Store and eventually following a direct link to the App.
It's incomprehensible to me how anyone not just a normal customer would out of their own free will sift through this virtual garbage can. Many of the apps you'll see in search are so obviously scammy and questionable looking, you'll even get the disgust you'd get from sifting through actual garbage.
Even if that were a goal, you couldn't reach it because there is only so much space. This would be a problem even, if we were to use what space is available, which is usually not the case for political reasons.
Improved technology won't help you and even changing politics wouldn't get you to this.
Currently you can't even really walk around in a room without being incredibly restricted in terms of room layout, furniture and let's not forget you the headset with cables attached.
Last but not least even this hypothetical virtual reality is still just that: virtual. Simply the knowledge that something is merely virtual will always be somewhat of a disappointment, the same way a copy, no matter how perfect, is not quite as appealing as the original.
The concept of Westworld has an authenticity to it, that virtual reality can never hope to reach. As humans we are just weird that way.
Unless we achieve the ability to essentially run a MITM attack on the brain, to intercept commands from the brain and to provide it with sensory input, VR won't come close to being something genuinely deserving the name virtual reality.
That Uber happens to be profitable and offer competitive prices doesn't imply anything for their prices in the future.
