What do you mean "hardest software to develop"? How exactly do you describe something that is hard/difficult? People are making AI for robots, you can now "talk" to your smartphone or computer, etc. so making a DC shouldn't be that difficult given the right talent.
As for "going in the right direction," right direction to where?
This bit did not make sense at all. You asked about software then you talk about technology (hardware)?
Just DCS is point of the spear in sim tech no? Dedicated coders in aviation, and no for just the money to code aircraft? 3rd parties taking some risk! but must be worth something? looking to some legacy for their time spent perhaps?
