I'm sorry but dozens, maybe hundreds of other questions were more deserving - this ama is about sending a rocket to mars not about their IT stack...

We are all a bit scarred after the IAC debacle, perhaps that explains the downvotes.

The IT stack was the cause of over a billion dollars of lost missions from leaving Earth all the way to Mars missions. It also is what will or won't get the rocket to Mars. So, it was worth an answer given that by itself has killed so many missions with the Moon missions themselves taking a huge team & cost to do right despite failures [which showed up].
