At 6 minutes into the talk, the slide suggests that their solution might be feasible (generating commercial power) by 2025.
The timeline at 12m10s says "could have a prototype reactor" in 5 years, and a powerplant in 10 years.
I didn't hear anything about actual success; mostly just optimism. Like, how does one get to Mars in 1 month, even with fusion power? What's the engine and how is it cooled?
For reference ITER is expected to get first plasma in 2020, a hypothetical DEMO electrical generator by (keeping fingers crossed) 2033, and a conjectured PROTO prototype power station by some time after 2050.
