It won't matter. Investment is hardly ever looked at in terms of total returns but only in terms of annual ROI as a percentage of the original outlay.

By "total" returns I didn't mean "lifetime" returns, but returns on the whole production to which the new technology can be applied (be it yearly, monthly, or whatever). My point is that, if we're building (or upgrading) bigger and bigger production plants, even a small improvement to the process can bring in big annual ROI.
