Our experience of mega-companies over extending themselves and crumbling are from a different period. Maybe.

And not all of them crumbled. Walmart did great.

But today we have A/B testing, Platform reuse for other business line(Cloud, site, Warehouses, trucks, etc), more predictable supply chains(ML), scary marketing techniques, small flat teams augmented by powerful tools, generous funding from the stock market, etc.

Now Amazon has it all. Their competitors ? not so much.
