whether or not these companies can turn a profit - time will tell. but I am betting that our massively profitable companies (which are biggest spenders of course) perhaps know what they are doing and just maybe they should get the benefit of the doubt until they are proven wrong. but if I had to make a wager and on one side I have google, microsoft, amazon, meta... and on the other side I have bunch of AI bubble people with a bunch of time to predict a "crash" I'd put my money on the former...
quite the opposite is happening as evidenced from last earnings reports…
