I disagree. Anyone working in a skilled profession can attest to the number of people who come to them saying that they have this "great idea" for you to work on, for free. It's never a great idea. Skilled professional have their own great ideas, and that's often the motivator for acquiring new skills to make those ideas possible.
Lowering the bar between idea and implementation, in a capitalist, surveillance/attention-based, target-marketed world further incentivizes low-effort, high-engagement practices and likely shrinks the space for high-effort markets.
Meanwhile the tools "lowering the bar" are rent-only or need hardware that is quickly becoming unaffordable. Silicon Valley's only play is enshittification. If it actually is successful it's only a matter of time before they switch from growth mode to profit mode and it's google search all over again but this time you're paying a monthly fee. If you want to have an idea of how that works out ask an adobe user-- and those were products that were already profitable. There is no way people are willing to pay the actual cost of ai, it will need to be extracted. The rest is externalities.
Not impossible. Just very difficult. Source: I lived there for several years without a car, moved close to where I worked (twice), biked and walked most of the time, some public transit when the routes lined up, had very little social life. If there was a special event across town, could use some money saved from not having a car to spring for a taxi.
