Boilers in large electrical plants look like modernist cathedrals. They can be ten stories tall, if not taller, with vertical ribs that are the heat exchangers. The "boogers" are the equivalent of soot in the the chimneys of lanterns, just writ large. They're the "slag" of the combustion process.
Table saws are no different from any other power tools. If you make a mistake when using them, they're unforgiving, with a capital "U", same as any other tool. The reason you hear of so many table saw accidents is that there are so many table saws. It's a really basic tool, and incredibly useful in many circumstances. The same applies to lathes. There are probably 2X as many injurious accidents on lathes simply because there are that many lathes, in comparison to other machine tools. It's just that basic a tool.
Saying that you'll never buy a particular tool is basically giving up on tools. They're all dangerous. There's no tool that somebody can't use in a dangerous fashion. Rather than disavow tools, just try really hard not to be that person. Really, really hard. Approach any and all power tools as if today is the day that you'll screw up and get hurt, and you probably never will.
