The "state of the art" looks a bit chaotic to people looking in from the outside, what with the variety of approaches being tested. But this is exactly how progress is made in science!
I'm glad to see that neutron blasting is being taken into consideration. I suppose not wasting most of your energy output as destructive radiation makes excellent sense economically, too.
With D-T the neutrons do heat a fluid, so it's not like the energy is wasted. For example, General Fusion would use them to heat a mixture of molten lead and lithium (the latter for breeding more tritium), which would heat water for a steam turbine. But aneutronic fuels put most of their energy into fast-moving charged particles, which lets you extract electric power without using a turbine.
