You definitely should do some degree, but it doesn't have to be a compsci one - is my personal take.
I did myself personally do a compsci degree, but to get into software it turned out to be quite unnecessary - if you are already building things and contributing to projects then just like being an artist the strength of your experience and your portfolio matter far more than your on-paper qualifications.
There's also the consideration that in computing especially, the industry moves so fast that a lot of what you learn at uni may already be old by the time you learn it, making actual experience and portfolio even more valuable.
In the company I work for, there are brilliant software engineers who have degrees in music and language, and even a former medical doctor!
Point is, if you want to get into software a compsci degree isn't the main factor. You should do some degree, but study whatever you believe will bring you the most joy and personal fulfilment - and if the answer to that is actually compsci then great.
