You forgot about fusion. I know it’s always decades away but I saw a very interesting YouTube clip the other day of a non-Tokamak fusion reactor (about 7 or 8 metres long and 2 metres or so in diameter) which avoids all the engineering problems of the Tokamak design. So one never knows what may be around the corner.
