Comment on Nowhere Is Safe by Tino

Wow...brilliant observation sir! One risk and another opportunity. Risk: short-term risks to structural safety and stability of everything above all of those underground tunnels, especially in urban environments. Compound this with climate change-induced flooding in the hastily urbanized, coastal areas where most of humanity lives and hence where more future wars will be fought. A return to Cu Chi tunnels of Vietnam War x 1000. Opportunity: dual-use technology. If a military industry of rapid, safe, small- and medium-sized boring machines can be developed, then this can benefit the hardening of civilian infrastructure and also make subway systems, burying electrical and telecomm cables more economical and safer...renaissance in urban planning and more liveable cities.
