They already have, significantly, around 25-35% in developed economies. The issue is that people often look at revenue, seeing company X earning $100 billion annually, and assume they should pay $20 billion in taxes. However, most AI companies today are not profitable and spend up to 100% more than their revenue on R&D and product development. I doubt they will turn a profit anytime soon, probably not for at least a decade.
Effective corporate tax rates were between 12 and 14% for the US, with some of the biggest corporations bordering 0%.

The thing is companies and even self-employed individuals of a certain wealth level know how to "(ab)use" it. From illegal but trivial and hard to detect tax evasion to financing personal lifestyle by having the company pay for certain luxuries (cars, computers, furniture, etc.).
If you have the wealth to have a dedicated office that dedicated office can be your man cave if you justify it with having all sorts of amenities for customers. And good luck to whoever checks taxes to find out how exactly things are used/not used.
All of that usually means that companies, company owners and high ranking managers get away with not paying taxes for a lot of things that everyone else does simply because they don't have a say within these companies.
And all of that is before you go to the tax advisor.
I am sorry, but if you do hard honest work the chances of you getting rich are beyond slim. Even worse when you do something that actually benefits society.
Actually it's much less, big corps are using any possibile schema to avoid paying taxes.
