Conviction level for which? For the state of the industry comment: quite high. Developers think too highly of themselves, their ability to reason (in general), and assume unjustifiably that this industry is somehow more merit-based and rational than others. For the particular arbitrage you describe: next to none. I know enough JavaScript and enough webdevs to know I don't care to know any more. I'll stick with data engineering, computational research, and systems programming, thanks very much.
