A lot of ecosystem eschew the debugger from their workflow. The best experience is with Common Lisp (slime) and Smalltalk, where you can inspect the variable from any snippet of code. It's quite nice too in IDEA (java) where you can put a breakpoint and investigate a suspicious behavior of a method.

Yes, but service technicians that are paid by the job often find ways to do a job in far less time using a different approach than the manufacturer suggests.

An example: I used to own a Saturn S-series. The manufacturer estimate for replacing the alternator was something like 4 hours of labor, and involved removing the power steering pump (which was above the alternator.)

It was possible to replace the alternator in about 30 minutes by removing the front passenger wheel and mud shield, and then accessing the alternator directly.

Manufacturer like to say things like 'use the repressor tool #4325' which is no longer produced and costs a small fortune, rather than a $5 bolt.

Of course, but most people don't have the manuals if they're fixing half broken rusty old winches
