When we install @angular/cli globally, we pin the version of ng binary to a specific version which results in us using out-of-date ng binary most of the times(Angular CLI team publishes new version on a weekly basis).
And if we are working in a team, we could be out of sync with the rest of developers since each dev might have different version of @angular/cli installed.
