From a human scale of energy needs over time, unlimited if the boring technology works.

People developing drilling technology for ultradeep holes also need to know something about the mechanics of geomaterials at the relevant pressures and temperatures. Quaise seems focused on developing drilling technology and are hyping it with implications for geothermal development that have nothing to do with the challenges of ultra-hot geothermal recovery.

That article is a fluffy hype piece on a drilling technology startup with an unproven application and with only pilot funding. More blurb:

Matthew Houde, a co-founder and geologist, remains undaunted. He notes that for millennia the Earth has shown us that stable holes of incredible depth are possible. Volcanoes draw their power from far deeper.

Houde is not talking about holes that have been drilled from the top down, but from the bottom up.
