I'm very pessimistic; MS tried this back in 2012 with Windows 8. Everything from Windows to SharePoint to Office and Visual Studio tried to adopt the whole Metro design stuff, but they ended up creating many inconsistencies. They made some minor changes when they refreshed it again with Windows 10 in 2015 and from then until 2022 (Windows 11), they had settled on Windows 10's design language, but now this attempt to refresh will just introduce more inconsistencies.
Microsoft has even more user-facing products in 2023 than they did in 2012, so it's probably going to be even worse.
The new version consumes hundreds of megabytes less memory. It consumes as much memory conducting a video call as the old version does when idle.

No, they aren't. They are adding another voice to the existing cacophony.
