This is not true.

1kbit keys are generally considered safe for now, although they may
become vulnerable to fantastically well-equipped adversaries within the
next decade.

2kbit keys are considered secure for what is effectively the indefinite
future.  We will not break 2kbit keys until we have had such massive
leaps in mathematics or engineering that they would deserve to be called
science fiction.
