A lot of people are saying the same thing right now, and the first half of it is true. With the tools I have, I can put out in a week something that would once have been a couple of months of coordinated work. Between the software, the generative help, and the bits of automation that finally hold together, the arithmetic really has changed. I have watched it change on my own desk, and it still surprises me some days.
That part gets said constantly. The part that gets left out is that the leverage doesn't come with judgment attached. It multiplies whatever you already bring to it. If your taste is good, the tools extend it. If it isn't, they just help you make more of the wrong thing, faster, and there is already plenty of that going around.
The tools give you throughput. They don't give you the sense of what is worth making. Throughput without that isn't really productivity. It is a bigger pile.
The other thing I did not expect is how tiring it is to be several people at once. The work compresses; the switching between the roles does not. In one afternoon I am the one thinking about strategy, then the one designing, then the one building, then the one sending the invoice, and while the machine will carry the labour of ten, there is still only one of me at the end of the day.
So the hard part turns out not to be technical. It is restraint. Taking fewer clients. Saying no to work that doesn't fit. Leaving some of the week empty on purpose, because the reason to have the leverage was to do better work, not simply more of it.
That last part is harder than the software makes it look. Most days I am still learning it.
