It’s a joke about software development tools breaking in dumb ways, and that it’s not a problem with saws

I’m a software engineer who does woodworking, and I approve this message.

But my favorite explanation: you grab your hand saw, and it works. You don’t find out that the latest npm japanese-hand-saw-tooth package is incompatible with plywood, and you need to downgrade the package or buy new plywood to make a cut.
