If I had to guess it would be higher amount of capital investment as a requirement and its impact on scaling - physical things can't just explode in-a-good-way the same way software can. This means both more time and more capital is required to scale up.

Incumbents benefit from economies of scale and newcomers face dis-economies of scale. Which we know takes time from the economies Growing new competitors becomes hard and requires some cleverness to get around. Just look at electric cars and how they choose luxury/sports cars as their first models for a reason, so that the higher costs can be hidden in the high luxury margins. They need to be able to grow past that awkward point.

The same economies of scale which made the industrial revolution possible essentially props up "gigantic idiots" (companies which perform poorly but are sizable enough that their economies of scale made up for bad habits) until their "stupidity" (bad decisions) becomes great enough a disadvantage that others can compete with them.

The type of disruption that the manufacturing companies seem to engender is funding outsourcing to some remote cheap locale, and then wake up wondering where all of their competitors came from after they taught people enmasse how to build their product.
