Why do you think that? Life on Earth has been around for billions of years and and yet we have no immortal beings nor all problems in physics solved.
There’s no reason beyond wishful thinking to believe any of that is true.
The Earth only developed intelligent life a few million years ago, us (homo sapiens) a few hundred thousand years ago.
We've only been in "technological takeoff" for ~250 years and are already using spaceships and computers to deliver and operate drones on Mars.
Now imagine 250 years + 1,000,000 years.
Everything we know and see has proven that progress is exponential.
Your statement that progress or intelligence is binary has no basis outside of intentional and ignorant pessimism.
