With standard near-surface geothermal energy, boreholes up to 200 meters are drilled. The heat difference from that depth is only around 10-15°C, but that's enough to collect the energy to heat buildings.
So yes, drilling into lava areas will spice up things.
I asked Bing your question, here's the answer:
"That's a very intriguing question. There is no definitive answer, but I can share some possible scenarios and implications.
One scenario is that AI content generation will become so advanced and ubiquitous that it will replace human writers entirely. In this case, the web will be filled with AI-generated content that is indistinguishable from human-written content. This could have some benefits, such as increased efficiency, scalability, and diversity of content. However, it could also have some drawbacks, such as loss of authenticity, creativity, and accountability. Moreover, it could raise ethical and legal issues, such as plagiarism, misinformation, and manipulation.
Another scenario is that AI content generation will coexist and collaborate with human writers, rather than replace them. In this case, the web will be a hybrid of AI-generated and human-written content, with varying degrees of quality and reliability. This could have some benefits, such as enhanced productivity, creativity, and accuracy of content. However, it could also have some drawbacks, such as confusion, bias, and conflict. Furthermore, it could require new skills and standards, such as critical thinking, verification, and attribution.
A third scenario is that AI content generation will be regulated and restricted, rather than allowed and encouraged. In this case, the web will be mostly human-written content, with limited and controlled use of AI-generated content. This could have some benefits, such as preservation of human values, culture, and identity. However, it could also have some drawbacks, such as stagnation, inequality, and censorship. Additionally, it could pose some challenges and risks, such as enforcement, compliance, and security.
As you can see, AI content generation is a complex and dynamic phenomenon that could have various outcomes and impacts on the web and society. It is not clear what will happen, but it is important to be aware and prepared for the possibilities."
