The main contradiction faced by all current software users： Endless feature additions and subscriptions 🆚 a limited budget. This is actually a cross-section of mathematics and philosophy. The total amount of money each of us can invest in the field of software is destined to not be higher than a certain upper limit, and the most commonly used parts have already accounted for a large part of it, such as google drive, icloud, netflix, office, etc., so there is not much left. (maybe only 50% or even lower of the total budget), more than 99% of the companies or products in the market have to compete. Thinking of this, product creators should try their best to create new incremental markets.
