Salesforce is a large and well-disciplined development company. It's pretty good at marketing too. It continues to innovate in all product areas, from core platform to applications, and the one criticism I'd make is that it's information overload at times. Lately Salesforce has made a big deal of adding its AI product, Einstein, to every application area to provide insights and stack rank options.

It can be a full-time job trying to keep up with Salesforce's newest cloud offerings. However, it is always worth the effort, because the company's pronouncements are often early bellwethers of the future direction of the software industry. This has become particularly true with respect to the company's evolving efforts to penetrate and gain a prominent position in the AI and IoT markets.

Facebook CEO Mark Zuckerberg on Monday used virtual reality tech to "teleport" to hurricane-ravaged Puerto Rico and soon was dubbed a "heartless billionaire" by critics who felt he had exploited the dire situation in the U.S. territory.

Watching Apple's product announcement showcase is a bit like celebrating New Year's. People from all over the world are drawn to this annual event with the promise of something new and exciting, a vision of tomorrow and untold promise.
