Re: Can someone parse this statement for me?
It certainly has the look and feel of corporate BS, but it may actually be quite sensible when you do parse it. My understanding is, "let's overprovision data centres today, presumably in specs and numbers alike, in the hope that we won't need more CAPEX investment for replacements for longer".
I assume Meta cannot easily do what just about everyone else does: swap CAPEX for OPEX by renting servers in the cloud: 1) major cloud providers are competitors in one sense or another; 2) Meta's scale is too huge; 3) Meta's requirements are too unique even beyond scale. So CAPEX it is, and optimizing that over time is generally a good idea.
Their adopted approach may or may not be right - one can only hope that they have done a deep analysis before jumping head first.
