For you it may not but for others it will, some ppl will mine cause they believe in the project, other will mine for "fun", other might mine cause they like the extra fan noise or want hot air blowing on their feet. Just cause you wont mine when it get's to that stage doesn't mean that other wont. You truly believe every person who is running F@H for example is doing it because they want to try and help out cure world disease?

If I wanted to get into professional mining I would be truly terrified by everyone who has free power, idealists simply supporting the project, ppl who considers their hardware "free" or wouldn't mind mining as long as there is a profit no matter how small. And let's not forget about all the additional costs involved when someone has to take their operation out of their mom's basement into the real world.
