Interesting, broadly speaking it could end up being another thing that fails to revolutionise the world in much the same way carbon nanotube, quantum computing, nuclear fusion hasn't, or atleast if you believed the hype. Once the devil in the detail comes out you see it's decades not year's away the media would have you believe.
Carbon nanotubes are difficult to construct on any kind of mass produced scale, so a construction steal replacement for skyscrapers and whatnot it hasn't. Quantum computing only useful in very specific circumstances, the sort of thing you' see billion dollar firms with it in basements but not home consumer products, it's not replacing traditional computer tech. Nuclear fusion is supremely difficult to sustain, we've still not worked out power transfer into form that can be inserted into the grid, eg steam turbine generator. Definitely won't be free to consumers or offer any kind of power revolution that means the world actually has unlimited energy.
Because there not possible tomorrow, doesn't mean they're not possible. Tech can sneak up quick, AI is improving daily.
'Decades' isn't really far away at all.
