I fear reinforced concrete disease and sea level rise will make housing disappear at a faster rate than people for the next 100-200 years. Conventional reinforced concrete is not like traditional stone buildings that may last centuries. The rebar inside rusts on timescales about ~100 years, and many buildings built over the XX century will be in bad shape and very hard to recover by the end of this century.
