>Plenty of places have had catastrophic droughts, famines, and plagues. Nearly half of Europe died a few times from plagues. Most natives in America were absolutely wiped out from disease and other issues. Tens of millions died of famine in China last century. Tsunamis washed away and killed hundreds of thousands in Indonesia and Japan this current century.
Conveniently you selected pre-technology examples. How curious.
Meanwhile the impending global famine(s) - (plural) of the 20th century never came to be because captitalism kept pumping out agriscience improvements to improve crop yields to 10 times what they were in 1900.
Technology can't save you from famines when there isn't enough sunlight to grow crops for a season or two. One good supervolcano and civilization might collapse or at least take such a hit as to be utterly transformed. Billions dead, etc.
The Green Revolution has so far just postponed famines. We are farming in an unsustainable way. We're running out of fertile topsoil and are depleting fossil aquifers in many regions of the world. Inorganic fertilizers might become scarce in the foreseeable future too.
You selected pre-climate change examples. How curious.
One thing worth noting about these agriscience improvements you're touting would be they require a combination of non-renewable inputs and unsustainable amounts of water. There is also the minor issue of unrecoverable topsoil depletion and the steady decline of nutrients in agricultural products tracked over decades. Kicking the can down the road isn't the same as solving the problem.

Technology has been around for hundreds of thousands of years. What are you defining as "technology"? Software as a service chatbots? Because those aren't saving anyone.
And 227000 people died 20 years ago in a tsunami in Indonesia. They had cell phones and the internet. Is that pre-technology? 50 million died in famines in China in the 1950s. They had TV, radio, and computers. Is that pre-technology?
Technology is just tools that humans make to solve a problem.[1] It's not magic. And in the case of the Japanese tsunami, the most basic technology that humans have had for tens of thousands of years saved countless lives: just building a wall, and making it tall enough to block rising water. [2] But wrapping an entire country in walls is kind of unfeasible. And you can't protect the entire world. We never know what kind of disaster will strike next, and technology to protect us only develops after we suffer the consequences at least once.
