I think the real breakthrough will come when we will be able to make powerful microbatteries.
I think there were some nuclear button ~~1W~~ 0.1mW ~~decade-long~~ 50-year batteries, from China if I recall

Not a new idea, although I don't think that particular isotope has been used before.
If only they could build say...a 15W nuclear battery that can last 50 years, THAT would be something. Enough for a very low-power smartphone, one who's CPU is clocked down so that it can't drain energy too fast. And ruggedized as well.
gee..if only we could charge our smartphones. It's expensive throwing them in the river when the battery drains.
Or some way to passively charge phones fast enough that they never need to get plugged in again. I hear one of the ways this would be done, would be by absorbing ambient radiowaves from telephone poles
