The actual fact that 1000th t20i took 14 years and the next 1000 took 4 years is so damn evident of today’s cricket world
Although majorly it is because all associates have t20i status now (easily inflates every year to have 15x the matches) , even the full member t20is have visibly gone up by miles
For ex Malinga took a decade to become top t20i wicket taker at 110 or so wickets and most players didn’t have more than 70-80
Now 2019 debut Adair and 2020 debut Rauf have like 100 wickets, Malinga isn’t Even top 3, Southee who was at 80-90 before Malinga retired is now at 150 because he continued to play. Arshdeep debuted in 2022 and has 90 wickets
5 match series is one real reason but even frequency of hosting t20 series has gone up
