Even if performance continues to scale, Moore's less famous second law about cost scaling is going to radically transform both semiconductor and consumer electronics starting around 2030. With balooning component costs denominating the value proposition (performance/($+power)) of new parts, hyperscalers won't find enough incremental value to warrant buying new chips (same for consumers with cellphones). This means parts will be used much longer and a robust secondary used market will substantially eat into revenue for the manufacturers. At some point the juice has been squeezed from viable architectural improvements and the technology fully matures into a commodity with a long service life (unreasonable to expect 10+% gains/year forever).
