Readit NewsI wonder if Pearl thinks that RL replicates his do-calculus under the hood, or if that's an innovation we're missing.
The big thing with calisthenics/gymnastics is developing the tendon and ligament strength in your joints which take several months/years, but is the foundation to doing the advanced stuff like planches and levers. Good luck!
Every business needs a business model. Subscribers is a very clear one. I'm untrusting of any service that's free and doesn't rely on ad-revenue, because they have incentive to make money in other shady ways like selling your data to third-parties who will use it against your best interests.
Subscriptions are a nice business model because they are predictable costs/revenue to both customers and the business.
What I don't like are subscriptions that don't grandfather you into higher pricing, and pay-as-you-go plans, because it's so easy to forget about then and their rules and get charged a nasty bill later.
As a customer IMO subscriptions are the lesser of all the evils, and the best alternative to ads, eg YouTube Premium.
