You and I aren't the ones in immediate danger. The service providers we rely on are. In discussions like these we have a "tragicomic" tendency to forget mankind's unstoppable progress. RSA-1024 offers 80 symmetric equivalent bits of security and we've been heading down this path for decades at an exponentially increasing pace.
Those service providers have had plenty of time to migrate to 2048 and most of them have already.

When it comes to compute, it's no faster than Moore's Law, which means roughly one bit of symmetric encryption every two years.

Given that the encryption security is itself exponential in bit length, we are in fact heading down this path linearly! (A doubling in compute power means the ability to crack twice as hard cryptosystems, which means ones that have 1 bit more of security).
Key must be extended over time, and they are, and have been for decades. A PoC of an attack of a security system broken since 1999 should be treated exactly like how we are amazed at little computing power was available to the Apollo program: this is a cool bit of trivia that shows the growth of available computing power, but not a display of any kind of security issue.
