I'm fine with this...this gives us some insight into what their plans are and how they're planning on improving Stack Overflow.
I should quantify this - from the announcement this looks like it concerns Stack Overflow at large, as opposed to the rest of the Stack Exchange network. This makes sense since that's what keeps the lights on the network on, and is easily the most influential network site by several orders of magnitude, no matter how you wanna slice the data.
From a value perspective, it's logical to invest into something which will provide more money or pay for other investments elsewhere. To put it in another way, there's no reason to spend $1,000 on a pet project when you can't make rent.
To answer the questions you posed...
Do you see that "the loop" can work and lead us to a "place" that works for "us" community?
It can, but there's a lot of calcified views out there. The big thing to balance (and this is a hard thing to balance) is that there are at least three perspectives to keep in mind at any one point in time - the community who uses the site (asking questions, getting answers and that's about it), the community who maintains the site (upvoting, downvoting, other moderation activities) and the company who, somehow, has to keep the whole thing paid for.
The issue I see is that there's a lot of noise in with the signal. I get that not a lot of us are happy that the company kind of disappeared on us for years at a time, and a lot of change has happened. I'm no stranger to that sensation.
However, the problem that needs to be solved is not an easy one - how do we make this community work for users who just want answers to their questions, users who want to maintain and encourage good questions, and the company who has to keep the lights on? On top of that, how do we balance the perspectives of all involved parties who have an obvious stake in this whole matter such that everyone can walk away feeling satisfied?
That's a process that needs time and effort and commitment from all parties involved. There's no silver bullet for that.
If so, how does your vision "on top" of "the loop" look like?
The big thing is that there will have to be compromise on all sides. The group of curators isn't always going to get their way, nor is the company or the group of others who ask questions, get answers and disappear. It's going to take time, and it's going to take a lot of energy to see and effect real change.
But it'll be slow. Not a lot of people are going to be satisfied with "slow", but I don't see this moving any faster than that.
