Achieving something for the first time is always hard...then it gets easier, more repeatable, and then very soon, everyone is doing it.
* synthesizing chemicals for example
* getting gas turbines to self sustaining took a long time, and many iterations, now you can go to a junkyard and get one made in a weekend...burning wood if you want. Look at the people trying to get self sustaining tuned length pulse jests.
these are big milestones, 1.5 time the energy input for a brief period...it will get easier...and it WILL get "mass" produced.
