On the other hand, infrastructure can only be as useful as the applications they support. Technologists love solving hard technical problems [1], but ultimately, isn't the main goal to improve peoples' lives? Almost all the engineers I know would prefer to work on sophisticated interesting problems than "another web-app," but there isn't much point if it is just for our own edification.

I can understand your disdain for Instagram's frivolity, but people said the same about Twitter and it ended up playing a major role in the Arab Spring, whereas almost no one outside the techworld knows or really cares who runs their infrastructure. Of course without this infrastructure it all wouldn't work.

Like you say, comparing the two is like comparing apples to oranges, you can't really argue one is fundamentally more important than the other.

Twitter is much closer to being classified as infrastructure in my opinion.

Instagram is a pretty much a self-contained service (i'll draw no conclusions about the frivolity it enables, just wanted to draw a distinction between the two.)

Improving people's lives can take many routes.

I do agree that "infrastructure can only be as useful as the applications they support" but I disagree strongly that "there isn't much point if it is just for our own edification". Advances are built on top of each other and some of them can seem obscure to the lay person. If no-one were pushing those boundaries we might not be in a position to discuss whether 'facetagram' is more impactful than 'instabook'. In that way, I'd argue that infrastructure is fundamentally more important due to it's multiplier effect (consider what EC2 has enabled).

I believe Marc Andreessan once said that Netscape wouldn't have been possible were it not for all the technology/infrastructure that went before it. He likened it to the icing/frosting on the cake. I can't seem to find the exact quote now though.

As I see it, there are those who explore combinations of what's possible to find out what's needed and those who make new things possible by solving hard problems.

I agree that we need both. It's just that we seem to get a lot of the first and not enough of the second.
