Agreed (I'm not a C.S. person, I'm a computational epidemiologist). This was mostly addressing the notion that because you don't need the LHC, or banks of PCR machines, or to enroll a couple thousand patients, that C.S. is somehow cheap, has zero costs, and zero pressure to get grant money. Postdocs, and computing time, and grad students, and your salary are all things that need to be supported by grant money. It might be easier, but to assert it's easy is flawed.
