HK, as a comparison, has preserved its character and charm, with life on the streets and many unique neighborhoods.
Singapore happens when you think SimCity is realistic: the primacy of the automobile, the belief that one additional Starbucks is always better than one marginal tree, the instinct that any public meeting must be broken up, unless it’s a queueueueueue (a long queue) at an Apple Store, etc.
It’s completely identical to Dubai or any of the Gulf metropolis, only with rain. The #1 Thing to Do in Singapour is taking the bridge to Malaysia, and never coming back. They think they can demolish the brutalism, but it’s already too late: it must be in the water supply. Anything built after ca 1980 is still brutalism, only with glass. When you get to Singapore, you take a $50 rise to the city center, and wonder why you are still in the airport.
Singapore is what happens when you don’t allow creative people the occasional drag of a joint: they take revenge, and make you live in it.
