Not contradicting your post 22, but passkeys make me uneasy. Give me a password that is strong that I store in keychain and I’m in charge of my own destiny (and access to the resource). 

Loose a device or an invisible crypto passkey and you’re buggered. #luddite  🤷‍♂️ 

There will be account recovery methods, just like forgotten passwords. If someone loses a device and hasn't backed up passkeys to the cloud, they'd have to recover their accounts with the registered sites. This can be done with emails, SMS.

If they are backed up to the cloud, locally or synced to multiple devices, it's much less likely people will get locked out.

If someone has 100 different passwords for all the sites they use and writes them down or uses a password app, losing those backups would have the same effect and would be much worse to recover as you'd have to think up all new passwords x100. Passkeys can be renewed with a click.

This new system will make it much easier to setup secure logins, people don't have to think up a new minimum length password, capital letters, numbers, special character etc. Just add email address, signup, verify email, save passkey.

Does Hide My Email for with Passkeys, or do you reveal your email address to the site?

There wouldn't be a need to use the original email address, Passkeys is just a file key instead of a password, everything else works the same.

As you said, “Just add email address, signup, verify email, save passkey.” I assumed you still needed an email. I guess it all might make sense if I tried it. 🙄

Hide My Email gives you an email alias so when you sign up to a service you'd use the alias, not the original address. Then verify the account via the alias.

Does anyone know of any software that can show me the load on my Neural Engines? Does anyone know why Apple's Activity Monitor refrains from reporting that data?

This app shows load on the Neural Engine:

The percentage isn't accurate but it will show when it's being used:

I doubt Apple is releasing an iMac Pro. An iMac Pro just isn't necessary with Mac Studio available. There might be a larger screened iMac coming but it won't be a Pro. Just because it's a larger screen iMac doesn't make it an iMac Pro. 

They would probably struggle to fit the Ultra chip into the chassis. The Ultra has a large heatsink that takes up most of the height of the device:



They wouldn't want to have the iMac that thick so this means they'd have to flatten the heatsink out and fit it with the two chips, fans, SSD, RAM into the chin area.

The old iMac Pro did it with the bulge at the back:



This was able to handle 370W, the Mac Studio Ultra is 295W:

https://support.apple.com/en-us/102027

If they want to get a similar profile as the 24" model and not put the parts behind the display, it would be more likely they'd top out at the Max chips (145W). This would mean it couldn't replace the Studio. It would also be really expensive, an Ultra iMac would be nearly $6k.

you guys seem not to understand how importsnt this announcement is for Apple Silicon and AI on the Mac! Mojo finally frees us from the tyranny of CUDA . You can go right to the metal instead of passing though other frameworks (Cuda has a stranglehold on AI and Nvidia doesn't support Apple products). So instead of bitching around about another language, read up on mojo and a good start is listening to the Lex Friedman's interview with Chris Lattner: https://m.youtube.com/watch?v=pdJQ8iVTwj8

Apple helped out here by adding Metal support to PyTorch and Tensorflow, Metal is the CUDA replacement:

https://pytorch.org/blog/introducing-accelerated-pytorch-training-on-mac/
https://github.com/apple/tensorflow_macos
https://developer.apple.com/metal/tensorflow-plugin/

Same kind of thing they did with Blender, which had CUDA/OpenCL and they added Metal.

While Mojo will help in other ways, it will still need special code similar to compute libraries like PyTorch, numpy etc. It needs the GPU driver and Metal API to do the work but they can abstract over it.

That video mentions it will take about 1.5-2 years to get the tooling in place to use it in projects.

It says here Lattner was trying to get Swift to replace Python in AI:

https://www.fast.ai/posts/2023-05-03-mojo-launch.html

This approach of improving Python performance using similar techniques in Swift makes more sense because so much AI code is already built on Python and it's an easier language to use.

They have been getting significant speed boosts out of the box and that's a huge benefit to normal Python users. The design of it looks good in that it should be able to run a normal Python project as is and add speedups where needed, like in the below example with over 80x speedup:
