If someone found a way to easily factorize large integers easily on consumer grade hardware then it would be very painful as RSA is one of the big public key algorithms.
Before you start worrying about it though consider that RSA has held up for 47 years of active cryptanalysis so far - during which time many alternative algorithms have been suggested as being superior, only to be broken a short time later.
Also the push to switch to Elliptic-Curve algorithms has been more down to them being easier for computers to use to encrypt/decrypt data.
Personally if I had to bet on which public key algorithm will still be around in 10 years time then I'd put my money on RSA.
