You might still think the analysis in the post is relevant if there are actors that can shape the incentive gradients you talk about: Google might be able to focus its sub-entities in a particular way while maintaining profit or a government might choose to implement more or less oversight over tech companies.
Even with the above paragraph, it seems like the relative change-over-time in resources and power of the strategic entities would be important to consider, as you point out. In this case, it seems like (known) fast takeoffs might be safer!
Yes, that seems an important case to consider.
