David Maintenance - **Spoilers**

So, having seen the movie, I have been puring over reviews and interviews last night and today. I noticed that in some of Michael Fassbender's interviews and he mentioned that David had not been able to get any maintenance or checking up done. That is not something I really thought about... I mean, do you guys think that is a key part of David's behavior in Covenant? Would there really be maintenance to be had? I just feel like this is important but I don't know how articulate anything right now. I''m still dazed from Covenant last night.
