In some ways the the Pharo fork/branch of Squeak Smalltalk might be seen as an answer answer to the related question of "How would Squeak (Smalltalk) for adults differ from Squeak".
One problem I see with Scratch is its slow pace in moving forward away from flash and toward something that is easy to self-host: cloud only is great until underpowered Internet at your local library forces kids to stop coding mid session. Flash can sometimes be a challenge to get to work reliably in a modern browser on a pc you might not have admin rights on (compared to something based on fairly conservative js, like https://www.lively-kernel.org/).
I've briefly looked at the Berkley snap!-project, and it looks a little easier to get into self-hosting and modifying (but I've yet to do so): https://snap.berkeley.edu/
In the same breath, I should probably also mention croquet/cobalt - although it appears no one has yet picked it up and ported it to the new generation of vr headsets:
It's frustrating to upvote a post that favours flash over any other
technology but I have to agree with you. I don't like this
always-online trend for all kinds of applications.
(generally spoken - I don't know the scratch situation)
