In a world where AI is no longer confined to screens and chatbots, humanoid robots are stepping into the spotlight—literally walking, talking, and working alongside us. I'm thrilled by the potential of these bipedal wonders. They embody the fusion of advanced AI, robotics, and human ingenuity, promising to tackle everything from labor shortages to loneliness in aging societies. Yet, as we stand on July 27, 2025, the reality is a mix of breakthroughs and challenges: costs are plummeting (think Unitree's R1 at just $5,900), but issues like battery life and ethical integration persist. Projections paint a rosy picture,

Investors are always on the lookout for opportunities in innovative sectors like space exploration and advanced semiconductors. Today, we're diving into two intriguing players: Rocket Lab USA (RKLB), a leader in small satellite launches and space systems, and Navitas Semiconductor (NVTS), a pioneer in gallium nitride (GaN) power chips for AI, EVs, and more. Both companies are in high-growth but high-risk phases, with current losses but promising futures. Based on recent valuations and market data as of July 2025, I'll break down their stock price estimates using methods like Discounted Cash Flow (DCF) and relative valuation, then compare them on

Electric vehicles (EVs) have transitioned from niche innovation to mainstream technology much faster than analysts predicted. In 2025, global passenger-car EV sales are expected to exceed 20 million units, accounting for over 25% of worldwide car sales. This growth will generate approximately US$780 billion in annual revenue. Industry forecasts project the EV market to reach around US$990 billion by 2029, potentially soaring to US$2.5 trillion by 2034. This positions EVs among the most dynamic sectors in transportation, energy, and capital markets.
