Ok, honest take from someone who is frequently nearby and walks through there semi-regularly:
1) Urban spaces draw you in, even if - actually, especially if - you don't pay money to be there
2) Urban spaces make optimal use of the space, coveting space as a precious resource
3) Urban spaces make diverse use of space
4) Urban spaces provide everything you need within walking distance
5) Urban spaces are future-facing: they provide opportunity for "whatever's next" to organically materialize within them
6) Urban spaces are not "all about business"; they are about living as much as they are about business
I am not an urban planner and respect the vastly more qualified perspective that dshoost and others have provided here. My highly unofficial and opinionated conclusion is: the jury is still out on this one, but things are not trending in a "this is great urbanism" direction; yet, there might be hope. Here me out, with the caveat that all of this is based upon "at present":
1) The central park is great. It's a semi-destination. However, with the exception of the snack shed (sorry, calling it what it is), the park is completely surrounded by unwelcoming blank glass walls, wide/expansive front entry patios, etc. All's not done yet...missing buildings will close in upon the park, better linking the park to its surroundings...and numerous vacant retail stalls will engage those in the park. None of this is there yet. What remains to be seen is whether formulaic chain retail is all that goes in here, or whether interesting local businesses move in.
2) I think this is a no / not yet. What's there now is based on near-term profitability for the developer, not long-term optimization for the population as a whole. Can't blame the developer; this is what zoning and planning are for. Will the planned but unclaimed parcels help change this?
3) Not yet. Not even close. However, not impossible in the future if enough people care...
4) Not yet. However, not impossible in the future if enough people care...
5) Not particularly; most of the buildings are specific-purpose-built biotech or residential. Then again, people can get creative with repurposing spaces.
6) Not yet. There's a half-hearted attempt, but it's not fleshed out.
So, there's reason to be hopeful. There's also reason to keep our standards high and not conclude this is good/great as-is.
