Well, I'm the sort of contrary person who reads random papers like that 
just for the fun of it. But when somebody says something like this, I 
don't think "ooo, that's scary", I think "ooo, somebody really ought to 
sit down and write a more gentle introduction". You really shouldn't 
*need* to know the exact implementation details to get some idea of what 
will perform well and what won't. But obviously you do need some kind of 
high-level understanding of what's going on. The STG paper isn't a good 
way to get that high-level overview.
