>long dead relatives talking to you in some memorabilia etc.

It seems a bit weird to me though. I mean, looking back at old records can still pass as mere nostalgic behavior. Wanting new sentences pronounced in disguise of lost relative voices is not great in term of respect for these people to share my own feelings.

Also I guess that now there is not much preventing completely new songs with whatever lyrics staring voices of Elvis, Hendrix and Pavarotti. Actually a continuous flow of on the fly generated lyrics seems perfectly plausible at this level, isn't it?

It is weird, and as usual there is a Black Mirror episode with this exact premise. The unforeseen consequences in the episode even seem pretty realistic based on current GPT behavior.

My grandpa wrote a fiction book so having him read it to me would be kinda cool, even if he's long gone. Still, he technically exists in the 4D universe but the time dimension no longer overlaps with mine.

Foreign language dubbing is a great use case. And the ability to alter the video such the the lips are synced to the dubbed version would be a great addition. I can’t believe studios are using these things already (the video part in particular).

I think we're not that far from the day all movies will be produced by AI, including all parts in various languages using the most popular actors per given market, all accurately translated and of course perfectly synced since there would be no dubbing but creation on the fly. First they'll use virtual copies of real actors by purchasing rights from their estate, until the public will slowly accept full virtual and cheaper ones. I give them 20 years max, and I'm being optimistic (pessimistic?).

About the blockchain comment… For years, I’ve been expecting camera makers (including phone makers) to offer image hash verification on blockchain at the moment of image capture. I’m surprised it’s not routine.

1. Expensive

2. Requires internet

3. What image do you verify? Between auto-retouching, manual retouching, compression, filetype conversion, an image file might be invisibly transformed 10 times in between capture and Instagram upload.

4. Useless for disproving fake images until every camera manufacturer in the world has implemented this.

5. Hostile to customers, now your picture doesn't get the green verified badge or whatever if you decide to crop it or something.

Ad 3) all of them. They will be recorded in a cryptographically recorded chain and you'll be able to backtrack all steps.

I'm now wondering how many images are generated a second that would all need to be recorded. How much is it going to cost to take a photo?

I don't think that works because there isn't One True Blockchain and it doesn't seem like there ever will be. How do you get Google, Huawei, some random photo editing app, Dropbox, Meta, etc. to all agree on the same chain?

This is a general problem that I have with a lot of blockchain ideas. For example, there are a few startups that claim to verify carbon offsets by registering them on the blockchain. There are many problems with this that we don't need to get into, but the relevant one here is: what is stopping me from registering the same offset on three different chains?

I guess a mix between impractical and completely useless?

The only thing that blockchain can do that couldn't be done before is cryptocurrencies (not sharing my opinion about them here).

Pretty sure this is not a good use of blockchain, and I don't see how it would remotely avoid misuses.
