It may be my software background showing but I think you are behind the times and most people associate "Silicon Valley tech industry" with computers nowadays.
My humble proposal is a giant statue of Mark Zuckerberg captioned
those idiots trust me with their data.
Seriously though, I'm curious what will come out of it. Having spent some time on American software forums, one thing I surely expect is drama, you can already get a taste of it from that article:
And some may wonder, in a city where the proliferation of high-paying tech jobs has led to rapidly-rising housing costs, whether that amount of money can’t be better spent on something more beneficial to those who are struggling.
There will be many who will wonder. And others will wonder whether it should be about software or hardware, or perhaps business management. And others will ask if a bunch of white males really deserve yet another monument. That's the reality of SV today, in my experience.
If I were to bet, I would say it will fail for lack of consensus and funding or become some "statement of unity and diversity" thing built by a small group of corporate donors like Google or Intel. But I will believe it when I see it.
