Perplexity for X, where X is a subject or broad domain

Perplexity has captured the world by storm for being a general purpose answer engine. When Google broke onto the scene, Internet users were already able to find relevant websites. There were countless directories such as Geocities and Yahoo and a bunch of other search engines like Altavista, Lycos, Excite and Dogpile to name a few.

There are so many that every new search engine that came out purported to differentiate itself as a quirky brand.

But what Google did was a few things;

Remove the categories under which websites were listed.
Removed all the flashy banners and sites and gifs and advertisements.

We went from standing in the middle of Time Square to standing in the middle of a zen garden.

Then it did a few more things.

Presented the user with a text box
Showed 10 links to choose from
Showed us that there was an ocean of information out there
Showed us that they got the most relevant results back to us quickly

It told us that we don’t have to waste time. We don’t have to miss out on relevant information.

Take a moment to go back in history with Google and their founding story. For all of us, Google is an important aspect of human history just like the discovery of electricity in modern times or the discovery of tool making amongst our ancient progenitors.

Then gradually we trusted Google to show us the most relevant result on the first slot.

We then spent time going to the website, reading through it, and back and forth we went about our work to arrive at the answer we were seeking.

Perplexity does the same. Take a moment to listen to the podcast with the founder of Perplexity. It will teach you a lot.

Perplexity does what Google did but solves a different problem.

Google assembled information from far and wide corners of the Internet. Google also scanned books offline, digitised large volumes of information from the offline world of print. And they made all of this available via a simple search interface.

Not only did this make the world's information accessible, they also improved commerce online with the invention of adwords and keyword bidding.

Perplexity is in the first phase of this unlock. Perplexity is developing an answer engine. Instead of you starting with a keyword, you can begin with a question. Instead of assembling the inputs for the final answer by going to a bunch of websites, you can get an answer immediately and verify the sources.

With AI we are unlocking a compression in our workflows of the mind. Cars compressed workflows of our bodies. If you had to go buy groceries, you could take public transport of various kinds and spend a certain amount of time. A personal vehicle could reduce this time spent. This came with a cost.

You not needing public transport or choosing to not use it may allow others to use. But your personal vehicle brings in net new consumption patterns on energy. It also brings in additional green house gas emissions.

The unlock here are robotaxis and fleets of vehicles run by robots that can act as your personal vehicle only when you need it. And when you don't need it, the vehicle can serve another human being.

These unlocks are happening rapidly in the world today both in the world of atoms vs the world of bits.

Below is a table that highlights two major “unlock” areas described in your text—one in the digital (information) realm and one in the physical (transportation) realm—comparing the traditional approaches/products with the new, innovative products that are “unlocking” greater efficiencies.
