The plumbing analogy doesn’t match software. You pay for a plumber once and you can always choose a new plumber. With software, it’s a monthly fee that will continue to increase over time. More features behind higher tiers. And probably taking and selling your data. So why wouldn’t a person try to build something custom for their needs? They have the ultimate feedback loop of actually using the product and telling AI the issue and having AI fix it. Most software people create are probably something they never used it their lives. But the best software comes from people building it that also use it. Even Shopify started when Tobi started a snowboarding store online and couldn’t suitable e-commerce software.
You’re right about people not watching plumbing videos and doing it themselves. But the equivalent example would be open-source software in the tech example. But instead of reading open-source code to see how different features were implemented, AI can go and dig into the code and figure it out.
