    Define “Space Travel” – we barely made it out of our atmosphere. Yes it’s “Space” but we really have not traveled any place, nor do we have the tech to do it. We do not have the right fuel, the right “Space Ship” to overcome what we could run into. Even Micrometeorites will kill the ship if we go any longer distance and chances to encounter increase. We have not enough speed to really go anywhere, Alpha Centauri – 7,000 years away with the fastest gear we got.
    Mars – minimum 3 years round trip at current tech levels – longer if we take a look around and the ship survives.
    Did we make progress – yes, but is it enough? We are not anywhere near a Type 1 civilization, and instead people looking at this as a global opportunity, we quibble amongst each other like schoolyard bullies. We have politicians with the foresight of a duck (might be insult to Ducks) and clueless what a Type 1 would entail. We cant get our act together knowing Global changes will kill us – yeah all excited about Space Travel….
    Just like a current global challenges, if we dont get off the ground, literally, in – by space terms – a fairly short period of time, when the sun expands – it wont matter what we did…… or how we did…… and no aliens will ever know we existed…

    A pressurized air system cannot exist directly adjacent to vacuum without dispersing.
    Enjoy your science fiction, kids.

Meet Wabi, the AI assistant with group chats, multiple threads, and an app-builder | Equity podcast

It seems like every big AI player is building a personal agent. Meta has Muse, OpenAI launched Dots, and a startup called Instinct recently raised $1 billion at a $10 billion valuation. But Eugenia Kuyda thinks the next generation of AI assistants needs to do more than book your restaurant reservations and find you hidden money in your Gmail.

Kuyda, who founded AI companion app Replika, has just launched Wabi, a personal AI agent that organizes your life into separate conversations, brings other people into the mix, and builds custom apps around what you’re trying to do. The idea is to make AI less of a solo productivity tool and more of a way to spend time with the people who matter to you.

On this episode of TechCrunch’s Equity podcast, Rebecca Bellan talks with Kuyda about why she thinks AI agents should bring people together instead of keeping them glued to a single chatbot, how Wabi plans to compete in a crowded and expensive market, and what it takes to get people comfortable giving an AI access to their email.
