Setting that aside, even if we accept your argument that gym costs barely scale with usage, then that makes gyms a bad comparison case for Anthropic, whose costs directly scale with usage. You can't use the gym model to defend Anthropic's pricing decisions if the two cost structures are nothing alike.
I'm arguing that both gyms and Anthropic have usage costs that scale with usage, but gym business model assumes a large margin of under-utilization and there's a hard cap to "power user" - I think both of those extremes don't apply to Anthropic's situation. Under-utilizers aren't paying for AI they have a free tier. There's also a natural ceiling on how much any one person can use a gym. There's no equivalent constraint on API usage.
Yes. In fact i remember hearing about a gym which offered a flat-rate pricing model but explicitly excluded certain professions from partaking in it. I remember the deal was excluding police, bouncers, models, actors and air stewardesses. They had a separate more costly tier for these people. (And I think i heard about it from the indignation the deal has caused online.)
Am I? I think you read something into my comments that I didn't write.
Sure they do. Free tiers suck. I may not always need to use AI, but when I need it, I don't want to immediately get hit by stupidly low quotas and rate limits, or get anything but SOTA models.
