The brief
Disruptive technologies often emerge with worse performance but better convenience, which is why established companies overlook them at their own peril.
The innovator's dilemma occurs when companies prioritize incremental innovations that sustain existing markets over disruptive ones that create new markets.
Christensen's framework of disruption explains how new entrants with new business models can outcompete incumbents with better products but higher costs.
Sustaining innovations improve existing products for existing customers, whereas disruptive innovations create new products for new customers with different needs.
About 50 percent of Fortune 500 companies from 1970 no longer exist today due to their inability to adapt to disruptive innovations in their industries.

Key ideas worth keeping

Innovation can be a curse for successful companies
Disruption is a predictable pattern
Convenience often beats performance
