This new release does seem to solve some long standing issues people have had with nextcloud for a while. Like great performance improvements and Federated Chat with Nextcloud Talk.
And improving Circles and renaming it to Teams seems like it's only gonna be really useful for Businesses. But I do hope that some smaller organizations can get some use out of it.
All in all, I think this release is great, if what they said in the announcement is true. I don't care much for all the AI additions, but I understand why they are doing it.
