I wouldn't buy that - if there is a dead switch then sorry, I don't want to pay that with my business.

Exactly! You can get a bare minimum, like a virtual machine (EC2) or storage (S3), which probably enough for small and medium enterprises (SME). However, if we move beyond, I'm not sure as I don't have experience with them. Now, if I'm building a prototype, I want something quick and just a lack of Cognito is a deal breaker.

The biggest elephants in the room are cloud providers, but I didn't find an easy alternative yet (hetzner, ovhcloud). ATM, the idea to the business is sold, that data resides somewhere near by in a datacenter, EU proximity. However, the EU businesses are realising that, well, whole region is at a mercy of one person.

Surprising?

Not one of these, but I tried on a small, Lithuanian, language. The catch is what the language has complicated grammar, but not as bad as Finnish, Estonian and Hungarian. I asked to summarise some text and it does the job, but the grammar is not perfect and in some cases, at a foreigner level. Plus, it invented some words with no meaning. E.g. `„Sveika gyvensena“ turi būti *atnemitinamas* viso kurso *vykišioje*.`

One way to test this is through a placebo test, where you shift the treatment, such as moving it to an earlier date, which I have seen used successfully in practice. Another approach is to test the sensitivity of each feature, which is often considered more of an art than a science. In practice, I haven't observed much success with this method.

You can apply it to estimate the impact of any business decision if you have data, so not only IT companies can benefit from it. However, the problem arises when the results don't align with the business's expectations. I have firsthand experience with projects being abandoned simply because the results didn't meet expectations.
