Artificial intelligence (AI) is one of the buzziest terms in technology at the moment. Given how complex AI is, it is hard to separate the pretenders from the real innovators. The industry is expected to grow at 20% annually through 2029 and hit over $1 trillion in annual spending worldwide. Companies that are the leaders in AI and machine learning can capture a lot of this spending, helping their businesses grow and leading their stocks to put up great returns for shareholders. Here are two AI stocks that look ready to make a bull run over the next decade.

LONDON – Helicopter cash, climate crises, smart cities and the space economy -- investors have all those possibilities ahead as they enter the third decade of the 21st century. They go into the new decade with a spring in their step after watching world stocks add over $25 trillion in value in the past 10 years and a bond rally put $13 trillion worth of bond yields below zero. They also saw internet-based firms transform the way humans work, shop and relax. Now investors are positioning for the tech revolution's next 10 years. Could we see a repeat of the Roaring '20, as the 1920s were known -- years of prosperity, technological innovation and such social developments as women winning the right to vote?

Robots are critical for expanding humanity off-planet. They help not just with exploring distant parts of the universe, but also with advancing our economic activity into Earth orbit. We spoke with Gordon Roesler, who formerly led DARPA's Robotic Servicing of Geosynchronous Satellites program. We asked for his thoughts on the potentials and difficulties facing space robotics, as well as how individuals can involve themselves in this exciting field. What are some of the most important ways that space robotics can make space more accessible, and which of these ways are most feasible?

The recent wave of technological innovations springing from the Fourth Industrial Revolution has opened up a huge opportunity in the space economy. Decreasing costs and a relatively open competitive field could mean huge growth; however, as a panel at the World Economic Forum Davos meetings this past January discussed, there are a number of potential pitfalls that could slow or even halt the growth of the space economy. The experts outlined the need for public-private collaboration, the innovations on Earth that have placed humanity on the threshold of this new frontier, and the possible downfalls the industry still faces. Here are the key takeaways. Public-private collaboration is the best way to foster growth in the space industry. The public sector may facilitate the growth of the space economy by building its infrastructure and absorbing some of its initial risk.
