Its very interesting to see the city change so much through the year. Lived in NYC for so many years, they will never stop rebuilding it. You think skyscrapers on 7th Avenue will be there 70 years from now? Once a new stronger materials will be invented with technology of faster elevators, these sky scrapers will be rebuild from new, most likely reaching 3x of current heights. So if you happen to be alive in 2099, check 2018s.nyc to see how New York City looked "before" :)
