Caps Lock Lyrics

Lyric discussion by CarlosHFF 

Cover art for Caps Lock lyrics by M.I.A.

is it only me who thinks that she is talking about technology? It's so clear to me that she is saying that sometimes she feels suffocated in the whole technologic world, and many in verses this feeling shows up.

Nobody send letters, everything is so superficial, so sad, and that's the feeling I guess is in the lyric.
