His reply was a bit too much indeed, but however I think it would still be great if you would be nice enough to state what you challenge yourself with. We'll be curious to see that it has something to do, even remotely, with famine and potable water (or other causes of the same sort).

So we are still left with the question ... what are you doing that's more useful to society than clock guy?

Go on?

I gave regularly to kiva,org, charitywater.org & local causes. I do the occasional programming volunteer tasks when I have time & find a fit (usually small things like giving web site support to small local charities).

On the side I'm trying to work more with #a11y & accessibility, as well as a lot of mentoring & teaching in programming

Sorry, I'm not a billionaire with too much time on my hands. With two teenagers that's the best I can do right now.
