Thats engineering. If you don't like it then try to make a career move into management or product or start your own company (not advised).
I myself had to come to terms with reality and have been making the transition.
You got one life, no use complaining until the day you die. Move into management and make the changes. If you're ambitious enough, you should have learned all you need to learn from engineering after 6 years and can apply your knowledge in a more strategic role, running circles around non-technical PMs.
