Laws of Tech: Commoditize Your Complement -
> Joel Spolsky in 2002 identified a major pattern in technology business & economics: the pattern of commoditizing your complement, an alternative to vertical integration, where companies seek to secure a chokepoint or quasi-monopoly in products composed of many necessary & sufficient layers by dominating one layer while fostering so much competition in another layer above or below its layer that no competing monopolist can emerge, prices are driven down to marginal costs elsewhere in the stack, total price drops & increases demand, and the majority of the consumer surplus of the final product can be diverted to the quasi-monopolist. A classic example is the commodification of PC hardware by the Microsoft OS monopoly, to the detriment of IBM & benefit of MS. This pattern explains many otherwise odd or apparently self-sabotaging ventures by large tech companies into apparently irrelevant fields, such as the high rate of releasing open-source contributions by many Internet companies or the intrusion of advertising companies into smartphone manufacturing & web browser development & statistical software & fiber-optic networks & municipal WiFi & radio spectrum auctions & DNS (Google): they are pre-emptive attempts to commodify another company elsewhere in the stack, or defenses against it being done to them

Complexity no Bar to AI -
Critics of AI risk suggest diminishing returns to computing (formalized asymptotically) means AI will be weak; this argument relies on a large number of questionable premises and ignoring additional resources, constant factors, and nonlinear returns to small intelligence advantages, and is highly unlikely. (computer science, transhumanism, AI, R)

Are Sunk Costs Fallacies? -
But to what extent is the sunk cost fallacy a real fallacy?
Below, I argue the following:
1. sunk costs are probably issues in big organizations
- but maybe not ones that can be helped
2. sunk costs are not issues in animals
3. sunk costs appear to exist in children & adults
- but many apparent instances of the fallacy are better explained as part of a learning strategy
- and there’s little evidence sunk cost-like behavior leads to actual problems in individuals
4. much of what we call sunk cost looks like simple carelessness & thoughtlessness
