Agreed that they should let agents shop. But matching the speed, efficiency and scale of Amazon logistics is the real challenge for any potential competitor to solve.

Amazon banning agents is the first opportunity I've seen since Amazon was founded for a startup to create an Amazon competitor. People will want agents to buy stuff for them. It will be one of the main use cases. And they won't want to use some Amazon-supplied agent to do it.

Am fashionably late, but it's been three months since I joined the design team @OpenAI! ☺️ It's been exhilarating and humbling to work alongside such brilliant people, on everything from small moments of delight to DevDay launches like dots. I feel very fortunate to have this opportunity so early in my career.

Couldn’t agree more, if it wasn’t the kindness of others, I wouldn’t be here today. DMs are always open 😊

@jayrizpopSep 26

if anyone reaches out to you for feedback or advice about design or their careers you should feel FUCKING LUCKY that someone looks up to you. recently I’ve had so many folks reach out and dm and I take time to jump on calls with all of them because shit is hard. be nice for gods sake.
