"This time is different" happened in 2008 when instead of letting inefficient behemoths crash and burn, they were bailed out. And before that, it happened around 2001, when Microsoft got away with a slap in the wrist after the Netscape thing. The big players of 2020 are entrenched much deeper and are much more in bed with the regulators, so it will take longer to level off.
I am also suspecting that the level-off will happen one layer higher. I.e. the economic relevance of the current incumbents within the US economy will not drop, but the global relevance of the US will. For a perspective, you can look at the German economy that is dominated by companies founded 100+ years ago.
