This is such a stereotypical HN post I almost don't believe it's real
* CLI tools with some wonky syntax
* You don't need X because there is a random github repo that solves your problem! (To be fair, this is within the hacker ethos/mindset)
* Assumption that folks can dip into savings or whatnot if they are over that month
* Assumption that folks _have a net worth_
* Assumption that it's easy to just "tighten up" if you're spending too much
This probably works great for a high earner with extra money laying around and a decent net worth. This would be terrible advice for someone who actually needs to follow a budget. A huge percentage of people are living month to month and don't have the option to loosen up or reactively tighten up after a month of too many expenses.
Some folks don't need a personal budget. That is the minority. Those folks can use wonky CLI utils to keep track of their life.
In that same vein, why even bother? Just add up your net worth and if it's lower than you want, just "tighten up"...
Terrible advice IMO.
