More precisely, it would be the immediate end of our ability to recruit competitively, and the slightly slower end of our competitiveness period, as faculty with options moved elsewhere. This is so because of the economics of faculty hiring. Particularly in STEM fields like computer science, those who become professors typically forgo vastly higher salaries in industry, not to mention equity in startup companies and so on.

We’re willing to move several economic strata downward in return for jobs where (in principle) no one can fire us without cause, or tell us what we’re allowed to say or publish. The evidence from industry labs (Google, Facebook, Microsoft, etc.) suggests that, in competitive fields, for Texas to attract
