Are you struggling to get your head around the various branding of AI? Consider that functionality can be built using the power of "AI" and that each functionality bundle can have a very different usage. The way it works, the way it is designed, the data that it uses, the reach and security that it leverages. Companies are working on communicating this, because for some audiences it matters.
In the world of "Business Think" the technology doesn't matter as much as what is being provided and how. If I have a specific need and that need is the same as another company, then perhaps, I just want to purchase something that meets that need. I don't necessarily need the technical details of how it is built, I just want the telephone system that allows all my employees to make calls, BUT just like buying a car, there are all the "you could also have" and "you might also need" or preferences such as color or in the case of a phone system, transcription, video, integrations, empowerment, security and the list goes on.
Microsoft has an interesting dilemma as the world gets nosier. They empower teams, business people, technical people, partners, independent software companies and others with the power to configure their offerings and not only configure, but choice of configurations depending on need and if there many choices are not enough, they also support, deeply support extensions to their code bases. Just like walking down the cereal aisle at the grocery story. 25 choices that are slightly different and you can pick your own ingredients and make your own granola (oats, raisins, brown sugar, nuts, bake).
Do we want choice?
Most of the time we do want choice. Try to be patient when considering that at times choices can be a bit overwhelming. Find your trusted souls, build your trusted network of gurus and most importantly have multi-person conversations on options.
The human knowledge wells are deep, if you can tap into these without egos, fears, games, societies current anxieties, you will have more power and more information than needed to make the right long-term choices.
