  1.  @makisekurisu4674  They do but like this copper interconnect story they rarely go past the research domain to make industrial manufacturing.

  2.  @gaboronem8615  don't listen to that pedant and barely intelligible bozo spamming all over the comment section. Jon covers historical topics, the RV disruption is just happening and there is not much to say outside the wikipedia page and media coverage.

  3. corrosion danger is one thing, oxydation is another and maybe silver is more reactive to the ambiant dioxygen. Silver layer also might be harder to deposit, to isolate and then to bond compared to copper. And it requires the same water pollution concern. Adding that to the price of the raw material you talked about, it could make it less practical and harder to scale. Heck! copper is already quite pricey nowadays despite being way more abundant.

  4. you've probably never etch copper at the nanometer scale… duh!

  5. it's toxic for the aqueous ecosystem, not us. Though ingesting copper sulfide (verdigris) is not recommended.

  6. with a rather inconsistent chemical etching method. die manufacturing requires to way more precision than this.

  7. omg you're right!
