Absolutely true.
And you make a great point that:
print(f"debug: {what_the_fuck_is_this}")
should absolutely be maturing intologger.log(SUPER_LOW_LVL, "{really_what_the_fuck_is_this}")
Unfortunately I have found that when print("debug") isn't working, usually logging isn't setup correctly either.
In a solidly built system, a garbage print line will hit the logs and raise several alerts because it's poorly formatted - making it easy for the developer to find.
Sadly, I often see the logging setup so that poorly formatted logs go nowhere, rather than raising alerts until they're fixed. This inevitably leads to both debug logs being lost and critical but slightly misformatted logs being lost.
Your point is particularly valuable when it's time to get the system fixed, because it's easier to say "logging needs to work" than "fix my stupid printf", even though they're roughly equivalent.
Edit: And getting back to the scripting scientist context, scripting scientists still have my formal official permission to just say "just make my print('debug') work".
