By chance, you do not provide any services related to marketing? Judging by your long posts, you are quite knowledgeable about this topic.

In order for the product to be sold, the buyer must learn about the existence of this product, and already here, most likely, the services of marketers will be required. That is, they can't be dispensed with from the very beginning.

Undoubtedly, marketers work wonders and manage to sell products to customers, even of dubious quality. Take for example hardware manufacturers (two leaders in this industry): trezor and ledger. Despite the fact that trezor doesn't have as many fails as ledger, ledger still manages to sell much better and remains the number 1 device (only in terms of sale, of course).

Actually, absolutely not. Our world of consumption has been swept by a wave of marketing influence, which is dominated not so much by good products, but by the most publicized ones. Better alternative products cannot enter the market against their background, which doesn't allow the development of healthy competition at the expense of product quality and, in a sense, hinders their evolution. The more alternative products appear, the better and better the products will be in the hands of the end consumer. But the problem is that this is almost impossible to do without marketing.
