Some of these happened on short bursts during the 20th century, the centuries before didn't experience life-changing technologies often. Also, things like genome sequencing or the fax haven't changed our day-to-day habits as much as the internet did.
More accurately, the "life changing" effects of new technologies (which are often a result of them being synthesized with other technologies and/or applied outside of their original context) took a lot longer to develop, largely because the spread of awareness of new technologies took longer. Which is why the frequency of the appearance of those life-changing effects of technology pretty consistently has increased as the speed and reach of information dissemination technologies has increased.
