From a young father point of view : SLS/SLA are not something home-friendly. The waste products and solvents are just too hazardous at the moment and will need robust integrated processes to be widely adopted. This will mean development, cost and most probably closed material packaging / software / ... Automatization on such scale means it will probably no longer be desktop.

The history of technological paths shows that end quality is not always the most deciding parameter for wide adoption.

My guess is that both will evolve in parallel and just as we have ink printers and laser printers, we'll have FDM and SLA offering 2 different options.
