The great displacement is already well underway?

It's no wonder that applications don't work. I can confirm this, but I just quit wasting time on them, went via contacts network.

What surprised me is that the OP had no reaction for personal messages.

I have seen people in similar circumstances that have enormous personal blind spots for issues that show up in interviews and with past colleagues. It's much easier to blame AI rather than admit or address those. If you have 20 years of experience and no one wants to work with you again, that is telling.

i got words of encouragement but no one had leads

Consider that that is what most people tell past co-workers who they don't want to refer

You likely need blunt feedback from someone you can trust in the industry
