For the most part, all the low hanging fruit that the great startups of the last 30 years monopolized on has been picked. The next 30 years will look nothing like the last. I suspect we'll be seeing much fewer sub 50 year old self-made billionaires, a near total collapse in the number of inflation-adjusted unicorns under age 10, and a relative shrinking of what we think of currently as "tech" in proportion of total GDP. We may even soon to stop thinking of software companies as tech companies by default.

Even looking at the last 10 years vs. the 10 years before that, the emphasis has already started to shift back the power to the celebrity content creator over the nerdy engineering tech creator. Before Web 2.0 really took off, websites and apps were all the rage because it was mostly nerds and other early adopters that could monopolize the power of the internet. Now the playing field has been leveled again, and it's those with strong personalities, marketing skills and other digital content production skills who have been making the big bucks. Mr. Beast's youtube channel was offered a $1 billion buyout. Engineers weren't thought of very highly before the personal computer revolution, and the money and power was all with the celebrities instead. I think the last 30 years was mostly an anomaly, but now that the internet is more democratized, the money and power will be returning to the celebrity content creator.
