Cost; specifically, power costs and scaling curves.
If you watched the video, you'd see Alex pointing out the disparity between the best dumb switch he could buy (30Tbps, 5kW) and the best firewall (120Gbps with some, but not all features turned on, using 2.4kW). Point being, he could run a datacentre with one switch using 5kW, but would need 250 firewall boxes using 600kW. And trends are driving the two apart; hardware firewalls aren't keeping up.
