ChatGPT has been around for a while now, and it hasn't led to a collapse in Google's search revenue, and in fact now Google is rushing to roll out their version instead of trying to entrench search.
A famous example is the iPhone killing the iPod, and it took around 3 and a half years for the iPod to really collapse, so chat and co-pilots might be early still. On the other hand handheld consumer electronics have much longer buying cycles than software tools.
