I think it's made me 3 -> 5x more valuable.
Now, maybe it's done the same for other people as well, but I think my co-efficient was high, and I continue to insist that I've never worked anywhere that had enough resource focused on software development. The demand has always massively exceeded the organisations ability to fund supply.
And, as many have noted lower costs can also boost demand.
Finally, off shore devs are on a longer cycle time for many reasons. If cost onshore are reduced then that cycle time will crush offshore competitive advantage. I don't see any prospect of me getting work from India or Indonesia, but I do see AI as a driver that will reduce work leaving the UK for other places.
