It's difficult to examine his comments without historical context: I haven't dealt with any code from that era, but there is still plenty of Fortran 77 code from ~20 years later where the use of gotos makes it difficult to understand control flow, e.g.: https://github.com/JuliaMath/openspecfun/blob/master/amos/zb...

That said, gotos are still occasionally very useful: jumping out of nested loops and implementing finite-state machines are both made much easier and clearer via gotos than trying to force them into more standard control flow statements.

The linux kernel also makes judicious use of gotos for cleaning up error handling: https://koblents.com/Ches/Links/Month-Mar-2013/20-Using-Goto...
