If labs are the only office people will actually inhabit going forward, then their presence is necessary if Kenmore and Downtown aren't going to be bedroom communities.
You write as if Boston has no depth of options - - as if it was one of those Amazon HQ2 contestant cities a few years ago who made spectacles of themselves and would have given Bezos every citizen's first born.
No. It's not "Either Or". For Boston, it's "We can chew gum and walk at the same time".
Labs are not the ONLY thing in demand. Something called HOUSING?
Boston/Cambridge/Somerville should be building tall residential skyscrapers in core areas (unheard of??? it's already happening - - see the D.1.0 res tower going up in Union Square or the about-to-be "tallest building in Cambridge". Labs are fine for Alewife, parts of Allston/Brighton, parts of Watertown, Suffolk Downs, Seaport Marine Terminal, etc.
So when you present the picture of : "If labs are the only office people will actually inhabit going forward, then their presence is necessary if Kenmore and Downtown aren't going to be bedroom communities." The first 12 words are already arguable. Because
1) workers are ALREADY returning (50-65%) to offices
and
2) Boston doesn't NEED offices to survive - - those buildings -and many more - can be residential......there is a demographic tsunami of Baby Boomers living longer/more active retirements and they want to be downtown and they want more restaurants/theatres/music venues/museums etc. Boston will become a 24/7 city that is FAR MORE vibrant and dynamic than a 9-5 commuter center.
Understand what a lab is in the urban sense. They destroy urban dynamism. I LOVE labs, hope more are built in Boston/Cambridge/Somerville, etc. and feel they are important IN THE PROPER urban planning locations....... "NOT FOR THE FREEDOM TRAIL."
Panicking and throwing in with building an inner core Ghost Town of labs is frankly a pants pissing act a Peoria or Allentown would have to resort to.
