While I don't agree with your premise at all, even if it could one shot a SaaS product (a statement so vague it's meaningless) I don't think there's much of an argument for why that's economically useful. A lot of SaaS has free software/open source equivalents anyway (how else do you think the clanker's are able to plagiarize it?). People still pay for Office even though you could easily use LibreOffice, or GitHub when you could self host Forgejo. It's like when anthropic made a big deal out of making a broken compiler. Neat, so, after ingesting all of open source and burning a trillion tokens you ended up with something worse than what's already out there; and instead of doing something economically useful like giving a person money to build it or supporting the open source ecosystem, you're just wasting energy on datacenters.
