The total capacity of infrastructure entities like AWS will increase by 10x at a minimum over the next decade. By comparison, your phone or laptop will modestly nudge forward. Consumers are not going to buy 10x the number of laptops, desktops and smartphones that they do today, ten years out. Most likely, those figures will barely move (the smartphone industry is already stagnating). Most of the incremental spending and investment will go into the centralized infrastructure by the giants.
Network speeds will continue to increase relatively rapidly. We can easily go from routine 50-100mbps home lines to 1gbps over the next decade. We're not going to see a 10x increase in the power of the average laptop (lucky if it doubles in ten years). It's primarily going to be useful for streaming/consuming very large amounts of data from epic scale central systems for gaming, 4K+, VR, etc. Decentralized systems owned by consumers will be far too weak to fill that role.
The AI future isn't going to be decentralized. The very expensive infrastructure that will demand, and its need to run 24/7, will be centralized and owned by extraordinarily large corporations.
It's precisely the typical consumer's home hardware that will act as the ultimate bottleneck guaranteeing decentralized can never take off. This has always been obvious, it won't prevent the fantasy from maintaining its allure of course. That will perpetually draw headlines and hype in tech, for decades to come, with no mass adoption breakthrough.
