I continue to hold and add to Alphabet here. There are some uncertainties moving forward in regards to AI replacing Google's dominant market share and search functionality, but Alphabet has been on this for quite some time and I do believe it is going to be able to transition its search platform into something that can compete heavily with many of the major LLMs.
The difficulty here could potentially be monetization. But, Alphabet has been very resilient for a very long time and has some very intelligent people at the forefront. So in this regard, I trust them to be able to manage this efficiently.
