Yes, it's a good question. I mean, also you've been around [indiscernible] people I've been around a long time. So you know that, yes, when we under invest, there's also going to be a knee jerk reaction, like it always happens. So this is more the shorter term correction of a miss planning that's happening today, that's what I call. It's the trend number one. But clearly, customers understanding that our capacity lead times, and our manufacturing lead times are long. So they do share with us a longer term vision. Now not 5 years out, this would be too much to ask, but certainly 2, 3 years out. So I mean, I would say, for 2022, 2023, we definitely have deep discussions about what they need in terms of expansion plans, in terms of what they see, when we talk about Logic, the anticipated capacity ramp in terms of the tape outs that they have on the shelves that they see coming on N5, and N3. So that -- it is not just some pie in the sky thinking. This is real underlying discussion that they have with their customers, and the design requirements that they get for increasing customer base, which has to do with high powered computer with AI and with all the applications that we talked about, because of the whole digital transition. So, yes, there is more visibility to the point that the planning system -- the planning visibility, is I would say deeper. And this is also where we've made our request to the supply chain on. It's of that discussion, which is going to be a costly discussion because you do not have capacity for nothing. So this is -- and it's also true for our customers. It's going to be costly, but they've been very explicit to the outside world and to the media about what their plans are. And that's well thought through based on what they see. So their customers, and the customers of their customers tell them. So this is why I talk about these three trends. And this is -- this basically is the base for the visibility, but how much in the end will be or we will need, there's always a risk of underestimation, but also risk of over estimation. And that's what we need to take into consideration when we say what's wise. And like I said, this is just something of the last 3, 4 months, where it starts to accelerate. It gives us a bit of time and our supplies, particularly to figure out what this wisdom.
