This was not my impression when I first learned about it. I thought I'd be using it all the time.
Just understating how git bisect works is the real superpower. The tool is a nice add on, but often you're right, is easier to bisect by hand by going to a known working commit and then doing a smart bisect based on the code you think might be offending.
But at least knowing the concept of bisection is a huge game changer.
Really feels like a stretch to credit git, of all things, with that fundamental understanding. It's like saying you need to operate a nuclear power plant to understand the benefits of locking doors.
