Also many times solving a problem people don't even realise they have, would still give immense value to the one who creates it, even though anyone could have created that software if only they thought about/identified the problem.
As they say, we will have a renaissance of software development
Case in point, PM management software (Jira), might be a very easy tool now for any company to make(a very naive stand, but in a world of ai not far fetched to argue), but managing and maintaining that software is still a chore, and it might not be in the interest of everyone to spend their effort on it. They might still prefer paying for it. Now, the product itself might die and some other product might take its place, but still that new product would be an individual thing. Atleast that's what I think.
