not really, fiber is still greatly preferred (For example: it's impossible to do 40Gb by microwave/millimeter wave, but a CWDM 4-channel 4x10GbE passive mux/demux on two strands of singlemode is trivial and very very cheap), or just a pair of 40Gb QSFP 10km reach optics using a single 1550nm wavelength between two routers or metro-E switches. But wireless can reach small cells, rooftops and towers that might be a very costly underground fiber build at $400-900/meter total construction cost to dig up streets in urban cores. It very much depends on the location.

Plus there's the reliability factor. With fiber you only have to worry about backhoe fade. Wireless has all kinds of fun failure modes.
Though with small monopole and cellular rooftop sites, MW can frequently be built in a ring or redundant traffic path configuration. Fiber to many endpoint sites like a cell tower is frequently a star topology network with one cable in a linear path along a ROW either aerial or underground.
