Constitutions are amended all the time. The French even have a proces for reboots of the Republic.
These are goods things.

It's original purpose, if I understand correctly, was to guarantee that fundamental rights were an essential part of the constitution and couldn't be amended away.
Wikipedia says that multiple countries appear to have adopted the principle: Pakistan, India, Bangladesh and Uganda.
Constitutions should be simple. They should delegate very little power to governments and focus mostly on constraining those governments. They should be changed very rarely.
Adaptable government with changing scopes belongs at lower levels of governance (mostly very local) or nowhere.
What keeps a country in check is not a constitution but a politically informed and active population. The US shows us right now that the constitution is just a piece of paper.
A constitution isn't just words, it creates a structure that exists in actual reality. The day before the tyrant comes you have multiple branches and levels of government. That stuff doesn't instantaneously cease to exist if they try to rip up the piece of paper, and its purpose is to fight against anyone who tries to rip it up.
If it fails at that purpose, your constitution contained insufficient checks and balances.(Notice that several of the ones in the original US constitution have been removed, and that was a mistake.)
