Don’t necessarily need to build taller, if transit (not bad in Paris already) is brought up to Tokyo levels (meaning an order of magnitude greater than anywhere else) then you just build densely outwards. Tokyo has far higher population but is mostly low-rise. A city like Paris has the bones for this.
impossible to brong it to tokyo level. our people are not educated like japanese people. add the strikes, the frequent infrastructure issues and we will never reach tokyo levels. also since covid transportation is worse since they figured out they could make more money cramping up less trains
