Sorry, but no. There's billions of people on earth; we can tackle many problems at once in parallel.

Yes, that's worked out wonderfully for us of late, hasn't it.

How would spending billions on the space race help?

Even if you didn't change anything about the software, the newer CPUs would still give you better energy efficiency and thereby longer battery life.

But the software devs will always more-than use up any extra efficiency, so it'll still barely last a day, and will die early when it gets heavy use...

This varies a lot from app to app. It’s true that some are built in a way that puts no thought towards efficiency, but there are plenty that are built by devs who care.

I like to keep around test devices that somewhat represent the average user’s device, and when it’s practical a low end device and test against those every so often just to make sure the app performs reasonably well.

This has been in my experience more important for Android apps than for iOS apps, though, because the gulf in power between currently-sold devices in the Android world is vastly more large than in the iOS world. With few exceptions, I find that reasonably efficient apps tested and developed chiefly on newer iPhones work fine on older iPhones, but developing and testing an Android app only on flagships will make for a miserable experience for users of low end or older Android devices.

It largely has, yes. The fact that things aren't perfect isn't justification for condemnation of the entire process.

In terms of usefulness and end user experience, I find no difference between the iPhone X (A11, 4 billion transistors) and my current 14. Seems to me that all that extra processing power is still looking for a use case.

Machine learning is that use case, it'll eat up as much processing power as you can throw at it. LLMs on your phone are a few hardware generations out, but they are coming.

ML/AI is not really a use case but rather a technology. The use cases may come a one point but right now, as far as I can see, they are missing.

For me there’s some benefit in little things like on-device OCR and image classification, which has been helpful for quickly surfacing particular photos in my library but yes the broad strokes have not changed much.

I am wondering about this; I have noticed the OCR (that you can photo something and the copy the text as plain text). How compute sensitive is that? Is that not available on the X? It is a useful feature. In particular in Google translate (lens function) which I am pretty was also there on the X (perhaps requiring a trip to Google’s server).

I’m not sure if it’s available on the X or not, but it would make a lot of sense if a certain level of hardware acceleration is required to do this OCR in the background with little to no negative impact on battery life. The X’s SoC can probably handle one-offs just fine, but it might not hold up as well to the OS churning through photos OCRing them in the background.

Photo/video processing

The iPhone X had excellent camera and photo/video processing. So much better than the earlier models; from the X up to today's model it is much more marginal improvements. Really nothing I notice as a casual user.

It's rare I find myself reaching for the adjective "Panglossian".

The features you use are not the features everyone else uses.

I think “For All Mankind” is a great “What If” show about what things would be like if we had kept pushing forward. The thing about the series though was that NASA was self funded and didn’t have to justify spending billions in taxpayer money. Also, do we really have better propulsion technology to make space travel more efficient?

Imagine if all of the worlds armament budgets were instead rerouted to science and space travel...

Whitey on the Moon / Lyrics

A rat done bit my sister Nell. (with Whitey on the moon)

Her face and arms began to swell. (and Whitey's on the moon)

I can't pay no doctor bill. (but Whitey's on the moon)

Ten years from now I'll be payin' still. (while Whitey's on the moon)

The man jus' upped my rent las' night. ('cause Whitey's on the moon)

No hot water, no toilets, no lights. (but Whitey's on the moon)

I wonder why he's uppi' me? ('cause Whitey's on the moon?)

I was already payin' 'im fifty a week. (with Whitey on the moon)

Taxes takin' my whole damn check,

Junkies makin' me a nervous wreck,

The price of food is goin' up,

An' as if all that shit wasn't enough

A rat done bit my sister Nell. (with Whitey on the moon)

Her face an' arm began to swell. (but Whitey's on the moon)

Was all that money I made las' year (for Whitey on the moon?)

How come there ain't no money here? (Hm! Whitey's on the moon)

Y'know I jus' 'bout had my fill (of Whitey on the moon)

I think I'll sen' these doctor bills, Airmail special (to Whitey on the moon)
