The point is if you have access to far greater scales of VC funds than most of us do, then build hard tech companies, not software, so you build a moat. You might note his company is named "Gigascale Capital"

So, sure, if YOU or I can access that capital, fine — availability is still scarce compared to access to AI to develop software, and you should build hard tech not software.
