Boring Company had announced in Feb 2020 that they had built Prufrock. They have been working on getting the machine to achieve its performance goals.

Boring Company started with a commercial machine from another supplier. It was called Godot and it was their first-generation tunneling machine. The Boring Company came up with Line Storm, a modified version of a conventional boring machine that is about twice as fast. The first major goal is to make tunneling 10X faster with Prufrock.

There will be further iterations of the tunneling machines.
