My main desktop is running on a 14-15 year old Intel Core i5 750 and I've got 20-30 google chrome windows open each with about 100 tabs (sorry I know... I'll clean them up eventually) and I photoshop all the time and multi-task with excel spreadsheets and VPNs and Thunderbird email client with 10-20 accounts, etc... And my numerous laptops are running on 10 year old processors just fine. I've got a 16 core AMD threadripper PC for intense cases but I haven't powered it on in months. It depends on WHAT you are using them for. Generally the public has reached a point where we don't need more processing power. Unless you're into gaming, streaming, editing, or a specific CPU intense use case we have enough computing power. The only thing left to do is make them more energy effecient.
