Tell me how you turned that fear into trust and what you learned doing it.

And that's a great question again, Randy, because before I joined HS2, I hadn't even heard of TBMs.

TBMs are tunnel boring machines.

And there are 11 tunnel boring machines across the UK.

And I was very privileged to be part of the launch of the two first tunnel boring machines in the Midlands, of which one was called Dorothy and the other was called Mary Ann.

a wide range of stakeholders were very skeptical of the two tunnel boring machines being launched.

And what these tunnel boring machines do is they operate 24-7, they operate underground, and they actually dig a hole underground, 10 meters underground, to make space for the actual train to actually the tunnel to go into this space.

So let me ask you as a father, not as a consultant, what do you want the governance and the equity infrastructure around dental AI to look like by the time he qualifies? And honestly, how far from that are we today?
