I believe you are most interested in marketing? I’ve mentioned this before, marketing is in a healthy tension with sales, to a degree they compete and undermine each other.
Sales do not want future products to be mentioned, unless they are in a new product category, as they give a pause, an excuse, for a current prospective buyer to not purchase today as there’s something better soon.
Marketing want to build up steadily an interest in a future product, using varied and fun methods and repeat the coming soon until it arrives. If anything, controversy, like it’s late, causes dialogue which keeps it in the minds of future owners, so marketing kind of like slipped product targets so long as products are not totally cancelled (as they pulled interest away from other coming-soon products). So a degree of controversy, mild annoyance is slightly net positive for marketing. Although straight up marketing people, in their DNA, are not consciously aware they are annoying, they swim a stream of consciousness of moving from fun to fun, and never look back or compare what was said with what was actual. So the fact you are noticing marketing mismatching actual makes me think marketing is not in your DNA.
Engineering is also in tension with sales and marketing. Engineering would prefer longer time to tweak a product, as every day they wake with a new idea to make a better product. A good engineer hates marketing, as what they said becomes warped from true to (often in error) not-true. e.g. “I said bluetooth 4.2 you said version 5, get it correct”
If you are interested in marketing, then understand the mear act of your words, of repeatedly announcements, and slipping, to a degree is deliberate marketing technique. While not wanting to annoy you, the fact you notice is keeping it in the minds of those reading your words.
These Live events only mention shipping product, so it’s straight up sales. Every question we ask about futures gets deflected, or with far off and expensive product replies.
Of the 3 skills: engineering, sales, marketing, the one I observe requires true genius is sales. Engineering is raw memory, learn electrical engineering and you’re done. Marketing is just hyperbole and never look back, Sales is tying a consumer’s needs and wants to a product, which is a truly rare talent and I’m not sure can ever be learned.
