D in AI Field

[Lasheen]

Hello, I'm a C programmer, and now i want to migrate to D.
i work in AI field, so i have some questions about D language:

1- is D suitable for mission critical systems(such as avionics 
systems) ?
  if (true){
2- what about safety, Security and reliability of D in Embedded 
systems ?
3- what about memory issues in D if i use it in AI ?
4- is there a compiler for AI ?
};
Thank you.
