We could use the unexpectedly high temperatures as a heat source for geothermal energy. Make money selling the energy for ten, twenty years,... until the temperatures fall and the rock becomes rigid. Then drill another kilometer, funded from the geophysical exploration budget.
Temperature too high again? Have a long pause to make a little money from geothermal energy.

Geothermal plants can trigger earthquakes [1], so it's probably unwise to build a lot more geothermal plants to meet global energy needs without addressing that risk first, especially near populated areas.
