Sentience, in the literature I have read has more to do with realizing sensation than merely having senses. A machine with a bunch of sensors is not sentient. A machine that knows it has a bunch of sensors may be. A machine that knows it knows it has a bunch of sensors is. If machine that says it knows it knows it has a bunch of sensors because it read this and is just repeating it is not. I think the google engineer is going to make a ton of money on the public speaking circuit and get a lucrative book deal for its manuscript. https://en.wikipedia.org/wiki/Sentience

Try to avoid playing GTW. Nobody lives long in that game.

Just Gravitons can be a heavy weight to bear.

Maybe they should start smaller?, small with an extinct Microbe and work their way up.

In addition:

A computer with a feedback loop is self aware. Being so it is a computer being. While a human being has human consciousness at least a self aware computer being has computer consciousness. A computer with computer consciousness that is aware of people has at least some non-zero potential for human consciousness.

when you have Unlimited Energy!!!

Sincerely, where is all the heat going to go when everyone uses all this free energy? The earth is effectively insulated by space, we're going to have to find a place to put the heat.

Could there be, or,what if there were black holes the size of the known universe?

SPEs materializing to follow the turtles all the way down.

Sandcastles fall into the sea eventually.

The "which isn't possible" annoyed me the most it is what it is. Each tock of the perfect clock an entire Universe is replaced with a whole new one. It kind of happens on a CPU at a much smaller scale, each instruction processed chages the whole. So goes my old tag line...

How did that slip through?

"one somehow capable of surviving temperatures in excess of 3000 kelvin, above the melting point of known metals"

Melting points of 4 known metals > 3000K:
Tungston 3683K
Rhenum 3453K
Osmium 3318K
Tantalium 3269K

K = C + 273.15.

A COBOL program peppered with a few unstructured GO TOs can be marvelously mysterious, especially when written either in haste or with a job security bias. Then there are those who profit purposefully making it more mysterious still: https://www.redversconsulting.com/cloaking_device.php On the other hand a well written COBOL program should be straightforward easy to maintain, and that isn't necessarily true for other languages.
