At the time, all of what we think of as the sea between Borneo, Sumatra, and Java, and on up to Thailand and Taiwan, and the whole South China and Yellow Seas up to Korea was all dry land, like a million square miles of it.

Borneo was high ground. Most of what was going on with humanity at the time, according to cave painting evidence, was there and is now almost all under water.

There is a hill on Java built over 20,000 years ago. Excavation was halted, by the Indonesian government, for reasons not expressed.

Sorry, how does ripgrep save you tens of hours? I get that it is faster than regular grep, but that doesn't really answer the question; I don't find myself stalled waiting for grep. The only reasonable explanation would be something ripgrep does that grep actually doesn't. I could try to guess, but have no confidence I would guess right.

You imagine there is no plan because you do not know about the plans.

It would be stupid to build storage there is not renewable generating capacity to charge. When there is such capacity, they will then build out storage. In the meantime the correct place to spend is on generation. Which, in fact, is what they are doing.

There are dozens of such reservoirs in the Sierra Nevada range in California. None of them will take as much water as Lake Mead, but they don't need to.

Sweden has lots of high mountains that may have shallow reservoirs built cheaply on top of. Reservoirs with earthen dikes are radically cheaper than the sort of dams needed for traditional hydro power, and may be placed almost anywhere, because they do not need or destroy a watershed. Lots of small ones, placed close to users, are better than one big one like Lake Mead.

Excess power is most usefully applied capturing CO2 and desalinating water. But nukes' operating cost is too high for that. Spending a single year's operating cost on solar, and then using solar to do that work,leaves you with all subsequent years' opex available to use building out more solar.
