Concerned about whether to wait for the updated macbook pro

someone just bought a computer and found that Intel released a 10nm chip, so the heart began to be extremely entangled. My suggestion is to buy as soon as possible, because forced by AMD, Intel may release 7nm chips in 2021: Intel plans to launch its 10 nm products in 2019 and 2020 and its 7 nm products in 2021. In the next year, people will continue to struggle with whether they will wait for 7nm, and then they will continue to struggle with 5nm. The iron law of electronic products update is that next year will always be better, enough is the king
