Backtracking: everyone in the field knows that backtracking engines (PCRE, java, dotnet, javascript, PHP, ruby, python..) are bad because they are the poster child of denial of service attacks. O(2^n) match time complexity is not good. most backtracking implementations are a combination of clever optimizations duct taped to a very slow engine - for simple cases it works well, but using a pattern that is not affected by the optimizations, you get to see what the “real” worst-case behavior looks like.
Before AI displaces the majority of jobs, there will be an interim period of human professionals having AI interns they are training to one day complete their specialized work, Khosla said. Meanwhile, while educational institutions may still exist because people like them, they will no longer be necessary to attain job-qualifying degrees like engineering. Instead, education, except for very specialized fields like heart surgery, will be free, and labor will become free as a result of AI’s ubiquity in workplaces.
