The recent UK Competitions and Market Authority report evaluating Google and the UK search market came to the conclusion a new entrant would require about 18 Billion GBP in capital to become a credible alternative search engine, in terms of size, quality, hardware, man hours making it.
Remember Cuil? Had the size, the fanfare but unfortunately not the quality.
Google pays Apple more than that every year just to set Google as the default search engine on iPhones.
In a way, Google is funding its future competitor.
Microsoft tried and failed to build a competitor and it's not like they have shallow pockets.
They grossly underestimated a number of aspects:
- The huge number of man-years invested in Google's search quality stack hand-tuning and what it would take to replicate it.
- The fact that the machine learning field was simply not ready to tackle the search quality problem.
- The infrastructure required to build a crawler / indexer stack as good as Google's
I think in 2020, the second problem is within reach of many companies technically. It's mostly a matter of throwing enough money at optimized infrastructure.However, replicating the search quality stack is going to be very hard, unless someone makes a huge breakthrough in machine learning / language modeling / language understanding at a thousandth of the cost it currently takes to run something like GPT-3.
The most likely candidate to execute properly on that last bit is - unfortunately - Google.
I don't see it that hopeless. I feel it kinda is like starting Open Street Maps. It won't be perfect for a long time but there will be people who'd prefer it and help out.
Of course they would - it would be set as the default search on their iPhones with no clear-cut way to change it. You know, "security". The users don't know what's best for them, etc. as Apple seems to think.
We’re already talking about building a search engine, might as well talk about a model to convincingly detect blogspam too.
