I mean, I wrote about how there were lots of interesting engineering problems between where we are now and this state. It is hard and it isn't cheap yet and I did not suggest otherwise. Perhaps saying "current promised tech" was confusing - I certainly did not mean "current planned tech" and should perhaps have said "current envisaged tech". But there is no fundamental reason that future costs of energy in a place like Australia won't be comparable to the current costs of the grid only (if all generation were free). That is effectively free compared to today's prices. This is why this field is fascinating to me - the potential benefits of progress which is theoretically quite easy (but maybe very hard in practice) is extremely valuable. Even if you don't think this end state is likely, it could still be very compelling to be involved in trying to get there.
