Generated lexers are still worth it but handwritten RD won on the parsing front. No other historical debate gets this Weekend at Bernie's treatment the way parser generators do. Is it from dated undergrad + research material? There must be a reason all the references and approaches in this article are decades old and parser combinators get a single dismissive footnote. Pretty sure that Guy Steele quote even predates PEGs.

Bison and YACC are a mess. Sure, go and complicate your build by introducing code gen steps and ancient spaghetti DSLs with terrible tooling and an extra learning curve. Anything to avoid writing a readable parser in the same language as the rest of your compiler. The amount of ink spilled over parsing and parser generators is phenomenal when you consider how trivial parsing is compared to the other compilation phases. Look at source code for large compilers and you'll find the handwritten parser is some of the easiest code to understand in the project. Lack of left recursion is a trivial limitation in practice.
