Jim Cramer says Alphabet (GOOG) - Get Alphabet Inc. Class C Report , (GOOGL) - Get Alphabet Inc. Class A Report "is not done going up," adding that the company has so many up-and-coming businesses beyond its core Google search engine that it would be "crazy" for Cramer's charitable trust not to own it.

"Sure, near-term revenue and earnings will be driven by online-ad sales, but the company is more diversified than that," Cramer said during an exclusive conference call with members of his Action Alerts PLUS Club for investors.

  • Self-Driving Cars. The stockpicker said Alphabet's Waymo self-driving car business is "leaps and bounds ahead of everyone else in the autonomous-vehicle market."
  • Artificial Intelligence. "There is no doubt -- and you can ask anyone other than perhaps the people in Nvidia (NVDA) - Get NVIDIA Corporation Report -- that Google/Alphabet is way ahead on artificial intelligence," Cramer said. He added that AI's potential "is so vast that it's likely to penetrate in some way, shape or form every industry on the planet."

"It's for these reasons -- other than online-ad dominance, which we think is going to be far less important down the road -- that we continue to like Google," he said. "And for the most part, [we] view pullbacks as buying opportunities. ... [Alphabet] is not done going up."
