I've published and sold my own software. I'm a writer (unpublished as yet, but I hope to use CC4 like Cory Doctorow - ethical copyright.) I've seen my software pirated; I've benefited financially from selling it. I know authors and their struggles with income.

And I agree. Copyright in its current form does more harm than good.

Copyright was introduced to counter genuine harms: there are stories of people publishing in the UK, and having what today we'd consider pirate copies of their books selling massive quantities in the US, for example, with the author seeing no revenue. I believe anyone who puts work into creating something, physical or non-physical, should be able to derive revenue from their work. But I also believe in the public good; that 'information want to be free' in that thoughts, ideas and stories are meant to be shared; and that in a fast-moving world long-term prevention of movement is harmful. I also believe that over time, protections meant for individuals become weapons for the powerful, and I believe we're there now.

Further, I worry that over the past decades to today, 'rights' are being socially redefined as property rights. We consider privacy, an inalienable human right, as something for us to be paid for by Meta. This is implicitly and silently treating an inalienable essence of being human as something to be bartered away, and I think a social retreat from the concept of property rights as being anything other than localised to, well, property, would help. Reduction or abolition of copyright would be a radical positive change in a general social attitude here.

Realistically, radically adjusted copyright (3 years for software, 10 years for a book or music?) gives both an opportunity for profit and allows reasonable expiration while still relevant. In the absence of that, yes, complete abolishment would be an upheaval but a net benefit to the world.

Changing copyright durations without touching patent law is useless. In your example we would also need to shorten software patents to e.g. 3 years. Otherwise the big fish will just create a patent maze.
