let’s take an entry level hobby electronics activity and do our best not to learn anything by using chatgpt??? what’s the point??

I would say the warranty is probably confidence that a percentage will last that long, and the amount they have to replace is cheaper than the business they lose not offering it.

edit: and no argument that companies are also working to make devices less repairable, i’m cynical that more often then not they are trying to design devices that last exactly as long as the warranty.
