What is the change in compression strength over years, decades? If there is a lot, it might fill small cracks, but at the risk of collapse it the ability to hold tons decreases. I'll keep good old concrete until the experimental stuff is shown to be stable for decades. What is outgassed over time? There are too many questions to simply dive in, let alone the increased cost.

Use it on the roads would be my choice, but cities will be too cheap to spend the money on it.

Why does the rounding look so jagged though? I don't think the grey edge helps.

I have the Galaxy S23 FE and nobody has asked me to pay for any AI nor warned me about any time limit for using it.

Where?
