If I'm reading their CEOspeak right, their objective is to fire the very experienced people, that costs a lot of money, and replace them with people that costs less.

I never worked at Google, so I don't know for sure, but it sounds like the Python team is important and that this will backfire. As the people that costs less will also be less skilled, and Python is an important piece for AI/ML research, where Google is already lagging behind. The AI people in Google will get lower quality help with Python, and Google will lag even further behind.

That what happens when the CEO is an MBA and not an engineer.

They are not stupid at all. Their interests are in conflict with the interests of tech workers and they are winning effortlessly, over and over again.

The big tech companies are all owned by the same people. If these layoffs cause google to lose market share to another company, it's fine because they own that company too.

What matters is coordinating regular layoffs across the whole industry to reduce labour costs. It's the same principle as a strike: if the whole industry does layoffs, workers gradually have to accept lower salaries. In other words, the employers are unionised and the employees are not.

This process will probably continue for the next 20 years, until tech workers have low salaries and no job security. It has happened to countless industries before, and I doubt we are special.

I'm sure the next big industries will be technology-focused, but that's not the same as "tech". They won't involve people being paid $200k to write websites in ruby.

It's going to be more expensive to hire and train new people when the dumdums in upper management finally figure out the mistakes

Unfortunately that's not the case. Those who have been laid off are those paid high salaries to build up the foundation. Now that the foundation is already there, they future work won't be as complex as before and need less training. So why would they still pay the very high salaries? They'll just get rid of the used-to-be-important programmers and hire the can-be-hired-for-a-lot-less programmers from India. It's sad, but that's the reality.

It's not dumb. They understand what they are doing. They think firing multiple people at once can flood the market with developers, and the situation could be used to hire new people with a lower compensation.

Don't think the rationale behind this is work quality or developer productivity. This is a power move. For Google and many big tech companies devs are replaceable and are just cogs in the machine. The problem is that they became too costly with the advent of COVID.
