Google and Mozilla Push for AV1 Image Format Adoption, Beats JPEG and HEIC
Google and Mozilla, the companies behind the Chrome and Firefox cross-platform web-browsers; are pushing for the adoption of a new web image format to replace the ageing and inefficient JPEG, and the license-ridden HEIC. The two companies are leading a consortium of Internet businesses, called the Alliance for Open Media, to push for the proliferation and standardization of the new AV1 image file format. Early testing shows AV1 files to be 15 percent smaller than HEIC for comparable quality, which in turn promises half the file-size of JPEG for comparable quality. Apple uses HEIC as the default image file format for iOS and MacOS, while JPEG, PNG, and GIF continue to be the dominant web image formats, and have been prevalent for over two decades now.
"It seems downright silly that we're still relying on compression tech from 20 years ago," said Kelly Thompson, general manager at 500px, a photo sharing and sales site. "The equipment we're using to capture and display images is now exceeding JPEG's upper limits." JPEG is not just inefficient, but also has severe color palette limitations, and lack of support for transparency. Adoption of newer image file formats could significantly reduce Internet bandwidth usage benefiting both end-users running on slower/metered connections; and for infrastructure providers, such as ISPs.

I remember Microsoft having a JPEG like algorithm with better compression and quality. But that also never took off. Similar fate is with OGG Vorbis. It's a great open standard, but it hasn't really been adopted beyond some music streaming stations and chat apps and in some game engines like Unreal. It's light years away from even coming anywhere near MP3. Or JPEG for that matter.
We'll eventually get a replacement, but it'll take time, mostly because of hardware devices that cannot be updated, but need to be replaced. And no vendor wants to gamble on it, making expenses and then not benefiting from it. Which is why everything takes so long...
And at this point, displacing JPEG will be as easy as displacing IPv4, JS or HTTP.
To hell with lossy compression for pictures.

I'm not a Programmer but i understand its Technically possible
On the other hand, programs executing portions of the memory that shouldn't be executed are what viruses are all about. However, in order to execute a part of the memory, the virus/bootstrap sequence has to reside elsewhere (not in the image, in this case).
Edit: For clarity, in memory executable code and other data are indistinguishable (i.e. they are essentially a succession of hex codes, if you want). Executing code means simply pointing to some location in the memory and telling the process: start running from here.
if image is loaded or Data into a Browser then the Browser runs the data
Or Do You Dispute that this can Happen ?
Remember the Crypto Coin Mining Browser Contraversity currently Circulating
And let's leave mining out of this, it really has nothing to do with the subject.Thank you, this is what I've been saying from the start: it's the decoders that should be under scrutiny here, not the image format itself.
