To summarize:

* questionable demand for AI products make the DC investments risky (makes sense)

* DCs being built in “remote” areas with cheap land may become obsolete/replaced by other DCs making use of said cheap land (questionable; DCs can upgrade cheaper than building a new one)

* financing for DCs used to be from Big Tech but is now spread out among private equity, sovereign wealth funds etc increasing the exposure of the economy to failure of these investments (again, questionable, unless they are being financed by bank loans)

The most salient concern seems to be a lack of demand. I don’t see why that would change in the future.
