Not very likely. People have been telling him to seek help and to look out for himself and his wellbeing for years now, and he is not willing to admit that he has any major problems in his life (even though deep down he probably knows he's a bit of a screw up and he's hiding from any major responsibilities that he comes across, when it suits him).
It would require some massive shift in his mentality to change and to recognise that if he doesn't want to end up homeless and couch surf between weens houses for the rest of his life, that be needs to completely drop the delusional grandeur that he's conjured up over the years and actually undertake some adult thinking (a monumental task for him, even a bigger one than moving a ton 10 dog house! figuratively speaking).
The awareness of mental health support is stagnate in the United States from my understanding and many homeless people find themselves in the situation they're in because they are impaired in some way and incapable of behaving like a regular citizen, for a multitude of reasons.
If Chris isn't careful and fails to seek out the right sort of assistance, even if it's handed to him on a silver platter from a white knight saviour, he could easily be like all those homeless people you have in San Francisco and Los Angeles.
His first step should be looking into section 8 housing for when the inevitable happens, but I don't even think he knows how to even go about this process at all, someone would literally have to hand hold him and kiss his arse in order for him to even attempt something like that as it stands now.
The irony in doing that actually is that you're not helping him in the longer term, in the sense that he should take care of these major life problems on his own, he'd be coddled up like a toddler whilst someone else organises all these demanding things for him (if he's really that incapable then that would mean there is reasonable grounds that he should have some sort of carer right? Well that's up for debate and as time goes on, his mental stability may get worse, but for now it all boils down to his laziness and his inability to think and act like someone his own age, and not use autism as a catch all excuse card).
