...because a year will have elapsed between now and a year from now :)
I started programming in the early 90s around age 10
And I was 10 years behind everyone who started in the early 80s. And 20 years behind everyone who started in the early 70s.
...and 10 years ahead of everyone who started in the early 00s
That's just math :)
If ChatGPT 5 comes out in a year, and you wait to start til it's here, you will be behind however long the developers of ChatGPT 5 have been working on it
AND you will NOT have a year of experience on ChatGPT 4 while waiting for version 5 :)
