    With wonderful technology, rain and moisture can be produced and targeted to specific areas to keep drought, famine and pestilence. Thank the wonderful agriculture science and crop dusters who changed from dropping toxic pesticides to life enriching nutrients that feed soil and crops. Where would Africa look like with out Jane Goodal! This is crap! Unfortunately it is also what intelligent people call propaganda !

    Amazing work! Using satellite data and AI to support farmers in Africa is a game-changer. Mapping crops, predicting disasters, and providing actionable insights can truly save lives and livelihoods. Technology applied with purpose can transform food security.

LLMs may have kicked off this AI boom, but the ceiling is closer than the hype suggests. As models run out of text data to train on, the companies and investors paying attention are already moving on. The next wave isn’t better chatbots; it’s machines that can understand the physical world. Luma AI, the Bay Area lab that raised over $1.4 billion from a16z, Nvidia, and Amazon, is betting on exactly that.

On episode of TechCrunch’s Equity podcast, we’re bringing you a conversation Rebecca Bellan sat down with Amit Jain, co-founder and CEO of Luma AI, at Web Summit Qatar. Together, the pair dug into where the next trillion-dollar AI opportunity actually gets built, and whether the companies chasing it even know what they’re building yet.
