Here is another possibility for something to work on. We are deploying IoT at scale without much concern for security. Effectively, we are building a massive weapon for our enemies to use against us -- one that is distributed, fault-tolerant, and built into our infrastructure. We would not be able to escape the consequences of such a weapon.

In addition to serving society, this would also be self-serving. I have to imagine someone working on this would become fairly wealthy or at least very eminent.

As far as I know, something close to nothing is being done about this problem.
