If we ever end up with a permanent base on the moon then it may be more feasible but at the moment I just don't see it

I'm putting it in the same category as Solar Roads and Hyperloop TBH... 

But I once put broadband over copper wire in that category 

 

I also (and I was Technical Director at the time) told the company there would never be HD video on LCD screens or indeed large LCD screens - and guess what then happened 

(I did do some good stuff, honest)

That's the trouble with predicting the future; nothing going to turn out as expected. As an avid reader of science fiction I can see that broad stroke guesses may point the way but getting the details right, never.
