Whats wrong with the Horizons tech? It looks great to me. If it aint broke dont fix it.Good point. The biggest issue here - I suppose - is that there is no realistic way to "evolve" present Horizons tech. It's a dead end as it is. So the only other way is to build another tech - on different principles. And I'm not as naïve as to suppose that any new tech will be flawless and as good as the old one after 5 years of corrections.
