Eh, the snafus'll happen, it's just they're most likely happen considerably less than they already do with human control if things end up being implemented as expected, which still seems fairly likely from everything I've noticed, m'self. Which is kinda' the point for most of it, insofar as screwups go.
Same thing with the accounting error, really... everything I've heard talkin' to folks that actually did that sort of bookkeeping back when it was basically entirely handwritten is that th'sort of errors like the one linked were considerably more common. And I'll say this on behalf of probably 90+% of accountants in the world right now: You try to take away our spreadsheets and databases and we are going to find you, and the budget for the police department that ends up looking for your body will mysteriously get reallocated. Not you in particular true, mind, but... anyone. Been taught and talked to folks that have been doing bookkeeping throughout the last few decades, who's been part of the slow transition... you'd take their arms faster than you'd take their computers. Having done a fair amount of bookkeeping either way myself, if mostly for practice, and, uh. I'm the same way. I'll take the occasional misplaced comma in a heartbeat if it means not taking hours/days/weeks longer, having dozens of other errors, and significantly worse off wrists to boot.
And yeah, it'll be pulling teeth to fine anyone, but... is that really that different now? Not so rhetorical question, mind... you'd know much better than me, true, whether the stuff you hear on TV about decade long cases to dig stuff out of companies that are incredibly clearly at fault are particularly accurate.
The job loss thing's a thing, though. Problem with or without full automation just due to steadily increasing production per worker, and you're not going have a very good time legally mandating inefficiencies in job positions, nevermind that you seriously don't want to considering our current and oncoming issues regarding resource use and conservation.
... though eeehhh, sonli, some database/accounting software gets pretty wonky. Sometimes they do. You double/triple check that stuff for a reason, heh. Is half the reason we're digitizing things like that so much; that double/triple checking can be the work of minutes/hours instead of days/weeks, heh.
E: Though apologies if any of that came off as particularly aggressive, true. That sort of thing's pretty close to the heart to me; I've been personally helping people dealing with folks resistant to digitalization and automation for a long while now, mostly related to education. It's incredibly frustrating to come back year after year to a half-week or better job of going through filing cabinets and hundreds of paper records checking attendance and whatnot, when you're entirely damn sure the entire process could take literally minutes if the bastards a position or two above would pull their head out their ass and let people put that crap to spreadsheet or database. I've literally offered to volunteer to do that work for a school system before, just to be rejected mostly because the administration was basically bloody luddites.
