Indeed. I keep around a 2015 MBP with 16GB (asked my old job's IT if I could just keep it when I left since it had already been replaced and wouldn't ever be redeployed) to supplement my Mac Mini which is my personal main computer. I sometimes use screen sharing, but mostly when I use the 2015 it's just a web browsing task. With adblocking enabled, it's 100% up to the task even with a bunch of tabs.

Given probably 80% of people probably use webapps for nearly everything, there's a huge amount of life left in a late-stage Intel Mac for people who will never engage in the types of tasks I used to find sluggish on my 2015 (very large Excel sheet calculations and various kinds of frontend code transpilation). Heck, even that stuff ran amazingly better on my 16" 2019 Intel MBP, so I'd assume for web browsing your old Macs will be amazing for someone in need, assuming they don't have bad keyboards.

My 2018 has a brand new keyboard and battery that I replaced myself. It's certainly still a good computer all things considered... but for a software developer, someone with means to afford a more modern box, I would def go Apple Silicon.

My 2015 Retina is running Arch linux as an experiment. That was kinda fun. I used it as a main dev rig for a few weeks years ago when the 2018 battery finally kicked the bucket.
