Hoboken and JC are close to Manhattan(PATH, bus, ferry) and as convenient as other NYC parts. Parking is difficult and traffic unpredictable often terrible.

Remote conferencing existed before Covid but now its just normal. Companies save money by having smaller flexible office spaces. Remote and flexible office hours means less demand for office space.

JC is not as expensive as smaller Hoboken but JC needs better amenities and safety.

JSQ area now visible from far and more buildings going up. With influx of people, JC can change rapidly or face an exodous after a year or two. Nowhere to walk unless JC develops some great urban spaces like Paris has.
