Is the lenghtening replacement cycle on mobile phones identical to the lengthening replacement cycle on PC’s from a generation ago? I recall in the early days of PCs software drove(compelled?) PC hardware upgrades every 2 or so years. Then hardware upgrades became unnecessary unless you were a hardcore gamer. Wouldn’t the same hardware/software relationship apply with mobile phone hardware? What’s the next compelling value proposition? Will a next generation AI/ML Assistant compel a hardware upgrade in terms of an AI focused chipset or additional sensors for data collection? Is there anything in the Chinese WeChat ecosystem that compels mobile hardware upgrades? How else can human vanity in terms of mobile hardware/software be exploited?
