I agree with many of the points in the article*, but don't come to quite the same conclusion. It really depends on what one means by the "Next Silicon Valley." As many have pointed out, the underlying factors and indicators are not very comparable, but if you're just wondering if Jax can attract young people and VC-type investors to the area driven by a burgeoning tech scene, then yes it could very well happen.
*"Accessible Financing" and "Robust Arts and Culture" are a bit overstated when this discussion is involving all the largest metros in the country.
