Why I have sold all my BRN shares – Worth a read for non-holders., page-71

Extract from an article in the FT today, again highlights how BRN's expenditure is relatively modest

"Google’s UK-based artificial intelligence unit DeepMind lost half a billion pounds last year, a similar figure to 2018, and its parent company Alphabet wrote off a further £1.1bn in debt, according to its latest accounts.The figures underline the huge investment that Google continues to make in the London-based AI team that it acquired in 2014 for about £400m, with the most talented machine-learning researchers able to command huge salaries.DeepMind’s revenues, which are derived entirely from applying its technology to commercial Google projects such as making its data centres more energy efficient and improving the voice of its virtual assistant, increased 158 per cent in 2019 to £265.5m in 2019."
