[Question] How common is it for one entity to have a 3+ year technological lead on its nearest competitor?

I’m writing a follow-up to my blog post on soft takeoff and DSA, and I am looking for good examples of tech companies or academic research projects that are ~3+ years ahead of their nearest competitors in the technology(ies) they are focusing on.

Exception: I’m not that interested in projects that are pursuing some niche technology, such that no one else wants to compete with them. Also: I’m especially interested in examples that are analogous to AGI in some way, e.g. because they deal with present-day AI or because they have a feedback loop effect.

Even better would be someone with expertise on the area being able to answer the title question directly. Best of all would be some solid statistics on the matter. Thanks in advance!
