Machine learning methods are really powerful for fitting predictive models and for doing classification on large-scale, high-dimensional data. These are the data we increasingly use in economics. So I think there's no doubt many machine learning methods will get used more and more often.
I think we should consider a Constitutional amendment that privatizes the Postal Service and nationalizes the wireless carriers. The Internet plays the central political, social, cultural and economic role that the US Postal Service once did.
The FCC predicts that demand for wireless connectivity could surpass existing capacity as early as next year, with massive deficits soon to follow, resulting in unreliable service and higher connectivity costs.
