Fair. Trouble is, we’re never going to get Graviton2 devices of our own outside of an AWS datacenter or device; the power profile is intellectually interesting, but not likely to ever enter the public sphere.
I'm not sure why Amazon won't try to recoup some of the investment by designing and marketing other boards / devices with this chip, or by just selling it in quantities to some manufacturers (think telecom, home entertainment, industrial equipment, etc).
Based upon my experience, I’d say it’s going to be profitable in its own right just by powering EC2 instances. The same argument could be said to apply to Apple’s ARM chips.

It does have an impact on operational cost, and cost is a very important factor.
I care because it's an interesting question regarding future trends in technology. More broadly, people care about a lot more than just what has direct short term applications to their jobs.
